# Field Energy of Permanent Magnets vs. Magnetic Monopoles

• particlezoo
In summary, when two permanent magnets attract, their magnetic fields reinforce each other, whether they are stacked on their ends, in which case they are pointing the same direction, or whether they are stuck on their sides, in which case the two magnets are pointing in opposite directions. According to the definition of the magnetic energy density based on (1/2)B^2/mu_0, the energy density in the magnetic field, according to this, would have increased, not decreased.

When two permanent magnets attract, their magnetic fields reinforce each other, whether they are stacked on their ends, in which case they are pointing the same direction, or whether they are stuck on their sides, in which case the two magnets are pointing in opposite directions. Everyone here knows that a compass will line up in the same direction as the applied magnetic field.

Since the total magnetic field energy is based on the square of the magnetic field strength, it would appear that the mean square of this field would increase as these magnets approached each other (or at least rotated to have mutual magnetic alignment), maximizing the average alignment between the magnetic fields over the whole spatial domain. Since this process releases kinetic energy, I would have to assume that magnetic potential energy should have gone down in this process. But from what I see according to the definition of the magnetic energy density based on (1/2)B^2/mu_0, which is not preceded at all by a negative sign, the energy density in the magnetic field, according to this, would have increased, not decreased. If both the magnetic field energy and the kinetic energy are increasing as two permanent magnets approach each other, it would beg the question of where the compensating energy change lies.

It is quite clear though if I have two electromagnets that in order to generate a magnetic field I have to expend electrical energy to develop the field in the first place, and then when I allow the solenoids to attract each other, the increase in the magnetic field energy energy due to (1/2)B^2/mu_0 is not without the introduction of back-emf which is clearly necessary to preserve the energy conservation. In this case, it is very clear that (1/2)B^2/m_0 (as well as kinetic energy) increased at the expense of my input electrical energy.

With the permanent magnets, we do not have this simple explanation as to why both these occur. Potential energy is apparently expended in order to bring the magnets to acceleration, but how could both the magnetic potential energy and kinetic energy increase in this process without something else in the picture? Something that is somehow expended as the permanent magnets are brought together?

I still think it makes sense that magnetic potential energy decreases as the permanent magnets come close together under attraction, just as we might find with approaching solenoids whose back-emf reduces the magnetic field of each solenoid, reducing the power consumption, but not the total energy already invested into creating the magnetic field. The problem is that there does not appear to be any mechanism by which the attracting and approaching permanent magnets could generate emfs into each other that could in any way act against the intrinsic electron magnetic moments. So I am left with a suspicion that the magnetic potential energy change would be negative.

Now, if I look at the potentials formulation of electromagnetism, it is quite evident to see where we might get a negative change in potential energy, say, if we have a moving charge q with velocity v in a solenoid acting against the magnetic field of a permanent magnet, which possesses a vector potential A. Reason being, the sign of the potential energy depends on the sign of q and A, as well as the cosine of the angle between v and A. However, using (1/2)B^2/mu_0 for the magnetic energy density appears to only give us a positive change in the energy density as the two magnets approach each other under attraction. The same problem arises if we use the expression for the magnetic energy density for linear, non-dispersive materials, (1/2)(BH), where B lines up with H.

To make matters worse, with permanent magnets, instead of a charge q with velocity v, we instead just have many pairs of electrons where one electron with its intrinsic magnetic moment orients in line with the field of the other (and vice versa), in a process which should release kinetic energy. But from what? And how does that fit into the potentials definition of the magnetic field energy?

Lastly, let us consider the case of magnetic monopoles, which are said to be analogous to electric charge, in that opposite poles attract and like poles repel. But how do we know that the opposite is not true? Remember that in the case of attracting permanent magnets, when they come closer together (or simply come into alignment), the mean square magnetic field rises, and therefore the magnetic field energy also rises. I would think this would be a binding energy, even if one were to replace the two permanent magnets with two solenoids with current. So the attractive forces which bring the magnets together will over time lead to decrease of the potential energy, if by potential energy we actually mean the potential energy that is converted into kinetic energy. If we applied the same logic to magnetic monopoles, then like magnetic monopoles should attract, as their merger would increase with the mean square magnetic field, analogous to the attracting permanent magnets. If so, we would, in converse, expect that opposite magnetic monopoles should repel. This makes magnetic monopoles less like an analog to electrical charges exerting Coulomb forces, and more like an analogy to gravitating masses. I have never found this to be described in the literature.

I know these are a lot of questions and concerns, but if you don't mind to answer at least some of them, that would be greatly appreciated. Thanks to all in advance.

Actually, when they atract their magnetic fields mostly cancel each other.

Which is precisely the reason that the original statement must be untrue.

The magnetic energy density is not based on B2, but on B2/μ ( not μ0 )

½*B2/μ = ½ * B * B/μ = ½ * B * H, so the magnetic energy density is also based on μ.

If you approach a piece of unmagnetized iron to a magnet, the iron will fill a volume wherein the magnetic energy density is smaller than outside said volume, because the relative permeability as for iron is, say 1000. So outside said volume, the magnetic energy density will be

Edens = ½ * B * B/(μ0)

whereas inside said volume it will be

Edens = ½ * B * B/(μ0 * 1000)

So approaching the piece of iron, the magnetic energy density will be weakened in said volume, hence the total energy.

This lost magnetic energy is converted to kinetic energy in the iron.

So if one were to insert a permanent magnet inside a coiled tube of wire and pass current through that wire, then what you are saying is that the permanent magnet would seek to cancel the cumulative magnet field generated by the wire, sort of like how an electric field generated inside capacitor's dielectric would cancel the electric field of the plates which polarized the dielectric? That's quite the opposite of how I was taught.

When the iron is not magnetized, B should be zero inside of it. When it is magnetized, B should not be 0 inside of it. Since you are squaring B, then clearly the average square of B would rise when the iron is magnetized.

In the case of my opening post, none of the scenarios involved situations where the differential permeability would necessarily differ significantly from unity. Example: Neodymium magnets (internal magnetization doesn't change much relative to the applied magnetic field [at room temperature]) vs. a magnetized steel rod (internal magnetization changes greatly to the applied magnetic field).

No, B is not physically squared, but mathematically:

Edens = ½ * B * H , H = B / μ →

Edens = ½ * B2 / μ

The squared B is just a mathematical reformulation of the equation. Physically the B is not squared.
Approaching a piece of iron to a cylindric magnet will not change the B-field significant in the surroundings of the magnet.

Example using ohms law:

P = V * I , I = V / R →

P = V2 / R

The voltage is not physically squared. There is no (square) transformer involved.

So physically, is the B of the applied magnet inducing the H in the iron, or is the H of the applied magnet inducing the B on the iron?

In the former case, I can see how the B of the applied magnet is a sense "reduced" by the soft magnetic material which has a relativity permeability above unity, so (1/2) B * H (using * for the dot product) should be less than (1/2) B * B / mu_0.

In the latter case, the H of the applied magnet is in a sense "increased" by the presence of the soft magnetic material. This is clearly the case for transformer, where the magnetic field of the current (the applied field) is clearly less than the field generated into the permeable core, which stores energy analogous to how a water tank stores water.

H is inducing B, like voltage is inducing current.

No, Ampere's law says:

circulation H⋅ds = N*I

Ampere says nothing about "soft magnetic material"/permeability. The H-field will be the same, high or low permeability.

But B = μ * H will change due to changed permeability, when H is constant.

No, Ampere's law says:

Ampere says nothing about "soft magnetic material"/permeability. The H-field will be the same, high or low permeability.

But B = μ * H will change due to changed permeability, when H is constant.

So in other words, the energy density is:

(1/2) mu_2 (H_1 * H_2), where "1" indicates the source of the applied field, and "2" indicates the permeable material affected (at the point where the energy density is measured).

Equivalently, this is:

(1/2) (H_1 * B_2)

However, what you said before sounded like:

(1/2) (B_1 * H_2)

Since you were dividing by the permeability of the material (i.e. mu_2).

Or did you mean:

(1/2) (B_2 * H_2)

What do you mean by: B_1, H_2 , etc.?

Hesch said:
What do you mean by: B_1, H_2 , etc.?

Say I have two permeable magnetic materials "1" and "2", so both have relative permeability greater than unity.

As you say, the H fields are not in anyway dependent on the presence of permeable magnetic material.

B_1 is different than mu_0 (H_1) inside "1", but it is the same outside of both "1" and "2".

B_1 is a function of position. So B_1 is weaker outside of "1" than it is inside "1", for two reasons:

1) The field strength decreases with distance

2) The permeability is lower outside

H_1 is a function of position. So H_1 is weaker outside of "1" than it is inside "1", for one reason:

1) The field strength decreases with distance

Permeability isn't a part of this.

So we have the field H_1 of "1" at the position where we wish to calculate the energy density. Let's say that position is inside of "2".

But say "2" has a relative permeability of 1000.

So we have the applied field H_1 from "1" affecting a domain inside of "2". This domain, like the rest of object "2" has a high permeability.

So:

(1/2) mu_2 (H_1 * H_2)

or

(1/2) (H_1 * B_2)

is our energy density in this case, where H_1 is the local magnetizing field, and B_2 is the local flux density. As you can see here, this quantity would increase with greater permeability, just as you would expect with current wrapped around an iron nail.

I'm sorry, but I'm not able to reply on that long post, due to that english is not my mother tongue. ( See my profile ).

particlezoo said:

The B-field is to be compared to electric current. The currents through two different resistors in series are the same ( Kirchhoffs's 1. law ). So the B-fields will be the same just outside/inside "1" ( no significant difference in distance ), but the H-fields will not, due to different μ-values ). This surface, that separates inside from outside is a pole. A pole is a discontinuity in permeabilty. That's why there is no poles in a toroid, though it may contain a magnetic field.

Say you have a liquid wherin a piece of iron is submerged. The relative permeability is the same in liquid/iron. Now you induce a strong inhomogenous magnetic field through the liquid/iron: The iron will never be attracted by this field because a movement of the iron will not make a difference in the energy density. There is no discontinuity as for the permeability.

Say you place a piece of iron inside a homogenous magnetic field, the iron will not be attracted anywhere, because if the iron moves, it will just move the location of a lower/higher energy density, but the total energy as for the all over system will be the same. Hence no lost magnetic energy to be converted to mechanical energy.

This is not right: If μr > 1 inside "1", the H-field will be weaker inside "1", because H = (constant) B / ( μ0 * μr ).

I hope somebody, speaking better english, will give you a more detailed answer.

The 1 and 2 subscripts don't matter. The energy density at each point is given by the fields and the material at each point regardless of whether the field is an "applied" field or not.

Yes. The force on the magnet will be in the direction that minimizes the cumulative field energy.

According to this then:

If B is fixed, then an increase in permeability would cause H to fall. That's because B=mu*H. So for a given applied B, H would be inverse to the local permeability mu.

If B were a function with time, then introducing a source of B closer to a separate material with permeability, would cause H to fall where the permeability is high, reducing the energy density according to (1/2) H * B, where H and B are those of the source of magnetism one is using to apply the field, assuming that B were the field being applied.

However, consider that "hard" magnetic materials can have a magnetic permeability close to unity, and with those, there is no excess permeability (i.e. magnetic susceptibility) to reduce the field energy in the way you suggest here.

In any case, how can B be independent from mu, when earlier you said:

Hesch said:
H is inducing B, like voltage is inducing current.

Where according to this, it is clear that H is being applied (i.e. it's the thing which is fixed).

Dale said:

Do you agree that there is a potential energy (component) between two permanent magnets in some way based on the dot product between field lines, integrated over the volume of interest?

Consider:

|C|^2 = |A-B|^2 = |A|^2 + |B|^2 - 2|A||B|cos(theta_AB)

Which is the simply the cosine law for a triangle.

In a location that the field vectors A and B are unaligned, cos(theta_AB) would be negative.

|A|^2 would be due to the source which generates A.

|B|^2 would be due to the source which generates B.

- 2|A||B|cos(theta_AB) would be the interaction energy, which would be positive in the case that A is opposed to B.

|C|^2 would be due to taking the norm of the difference between A and B.

- - - - - - - -

But I was thinking that the energy in the field is really dependent on the squared-norm of the sum of A, B, etc., not the difference, since like you say, it doesn't matter which one is "1" and which one is "2".

|C|^2 = |A+B|^2 = |A|^2 + |B|^2 + 2|A||B|cos(theta_AB)

Which is the simply the cosine law for a triangle (with vector B swapped).

In a location that the field vectors A and B are unaligned, cos(theta_AB) would be negative.

|A|^2 would be due to the source which generates A.

|B|^2 would be due to the source which generates B.

+ 2|A||B|cos(theta_AB) would be the interaction energy, which would be negative in the case that A is opposed to B.

|C|^2 would be due to taking the norm of the sum between A and B.

Based on what you are saying, is it the quantity (1/2)|C|^2/mu_(x,y,z) or the (1/2)mu_(x,y,z) |C|^2 that should be integrated over space, where "C" of the former is the "B field", and "C" of the latter is the "H field"?

H doesn't have to be fixed.

Say you have two resistors in series ( different values, but equally sized ), the currents ( B-fields ) will be the same but the inside electric fields ( H-fields ) will be different.

The previous mentioned Ampere's law says that the mean strength of the H-field = N * I / s, and can not be used to calculate the strength at a specific location.

It wouldn't be C in either case, it would be the sum of A and B, not the difference. However, whether you use H or not depends if you are using the microscopic or macroscopic Maxwell's equations. As long as you are consistent you are fine.

If I took two identical loops of wire with identical currents, and if I were to orient them in the same direction along their central axis (like two wheels on an imaginary axle), they would attract, would they not? If I measured their mutual inductance, would this not increase from 0 to some positive value in Henries as they approached each other from infinity? Wouldn't I have to apply more power to keep the current constant given the back-EMF we know will be induced? If I wrapped these loops around iron disks, would not their field be oriented in the same direction as each other? Would not these magnets reinforce each other's magnetic field the same way the loops did such that the total field was not zero but rather more or less the sum of the two fields which point the same way?

Yes.

particlezoo said:

No. They partially cancel each other's field. That is precisely why they attract.

Near the south pole the radial component of the field points in and near the north pole it points out. These cancel each other out leaving a purely axial field which is much weaker and therefore has a much lower energy density.

particlezoo said:

They don't point the same way everywhere. Remember, it is the cumulative field energy, integrated over the whole field.

If have two currents in parallel, what do you think they will do? They will attract. The field between them cancels, and the fields outside are lined up.

As it turns out, when you have two opposite charges attracting, there is an imaginary sphere outside of which the fields differ by an obtuse angle (i.e. they are "unaligned") and inside of which they differ by an acute angle (i.e. they are "aligned"). So clearly in the case for electric charges the outside fields matter more than the inside. Why not for two electric currents?

So this tells me that it is these fields on the outside the space between the two current elements are what matter, not the fields in between them.

Monopole fields fall off at a different rate than dipole fields, and differently than a straight wire.

There is no reason to assume that the results of the integration will be the same. You just have to actually work out the math.

Yes, that would be the best approach, but I would have thought that if I have a coil producing a magnetic field which from the center field points to the ceiling that a magnet in the same place would also line up to point towards the ceiling. You've been telling me that it doesn't, that it points the other way. For the magnetic field to point the other way sounds like diamagnetism to me, where an applied magnetic field generates magnetic field in the opposite direction.

In the case for two collinearly-oriented, laterally-separated current elements, the fields drop inversely with square of the distance from each and the cosine of the angle away from the perpendicular plane from each. Any unalignment between the fields of each would be purely in the plane perpendicular to motion. The volume of an imaginary sphere between them would increase with the cube of the distance, and average the energy densities would drop with the fourth power of the distance, such that the total energy in between tends to scale inversely with the distance. Since the fields where the angle from the plane is large are minimal, this would roughly scale the same way even if the current of both were infinitely long. So therefore, conversely, the energy in this field would become greater, in a way inversely proportional to the distance, but since that term is negative, it confirms your statement... unless the field energy outside increases at least as fast, which it might.

I haven't been telling you that. I have never even discussed that scenario. I was discussing the scenario where they are spatially separated so that there is an attractive force.

In the scenario where they are at the same location there is no force. It is in a minimum-energy configuration and the force is 0 unless you displace them.

Bottom line, I am telling you that the cumulative energy density integrated over all space is what you need to pay attention to. That is the general rule that you need to apply consistently.

And is this irrespective of which way the magnet is pointing? I would figure that we would have a saddle point in the case that the applied magnetic field was exactly opposite to the magnetic field of the magnet. If the shape of the permanent magnet's field conformed exactly to the shape of the field of the coil and that the current was completely smooth such that there are no singularities, and "passable" so that the magnet could run right through them, it appears to me that the magnet would line up with the applied field, as if it were some really large magnetic domain which contributes to the permeability. If this were not the case, the magnetic field produced by an electromagnet with a core would be reversed of the case without a core, unless you are suggesting that the magnetic field of the core is reversed inside of it relative to its outside (which is only possible if there are magnetic monopoles).

Dale said:

Agreed.

One simple argument to favor the idea that the magnetic fields align together rather than against each other involves this thought experiment:

Say you have a compass needle and you orient it with respect to an external magnetic field from a bar magnet. Then fix the position of the compass needle. Now place another compass needle in a direction along the same magnetic field line. After that, pin the position of that second compass needle, and remove the external magnetic field. Now release the pin from the second compass needle only. If the field of the first compass needle is truly reverse of the applied field, then the second compass needle should now rotate 180 degrees.

Here is another simple argument to suggest that magnetic field lines tend to line up rather than cancel:

Start with a bar magnet and a uniform magnetic field. Now replace the uniform magnetic field with an approximately uniform magnetic field from a distant bar magnet pointing in the same direction as the original uniform field. This guarantees that the interior of the distant bar magnet has the magnetic field pointing in the same way as the original field. Clearly this distant bar magnet points in the same way as the first and will not cause it to flip. Therefore the original uniform magnetic field was aligned with the interior of the first bar magnet.

I am glad to leave it at that then. All the rest you can work out on your own. I have lost interest.

Since you are continuing to post misinformation, this thread is closed.

## 1. What is the difference between field energy of permanent magnets and magnetic monopoles?

The field energy of permanent magnets refers to the energy stored in the magnetic field surrounding a magnet, while magnetic monopoles are hypothetical particles that have only one magnetic pole (either north or south) instead of the usual dipole configuration of magnets.

## 2. Can magnetic monopoles exist?

Although magnetic monopoles have not yet been observed in nature, some theories in physics suggest their existence. However, it is still a topic of ongoing research and experimentation.

## 3. How do the field energies of permanent magnets and magnetic monopoles compare?

The field energy of a magnetic monopole would be much stronger than that of a permanent magnet. This is because a monopole would have a single pole, while a permanent magnet has both a north and south pole that cancel each other out to some extent.

## 4. What applications could magnetic monopoles have if they were discovered?

If magnetic monopoles were discovered and harnessed, they could potentially have a wide range of applications in fields such as energy storage, data storage, and medical imaging. However, more research would be needed to fully understand and utilize their properties.

## 5. How are scientists searching for magnetic monopoles?

Scientists are using a variety of methods to search for magnetic monopoles, including particle accelerators and detectors. They are also studying natural phenomena, such as cosmic rays, for any evidence of monopoles. Additionally, some researchers are exploring the possibility of creating monopoles artificially in laboratory settings.
