Do electrons flow in one direction in magnets?

In summary, magnets do not depend on electric currents to generate their magnetic fields, but rather use the angular momentum and intrinsic spin of electrons to align the magnetic fields of each atom. This results in a noticeable magnetic effect. In an electromagnet, the flow of electrons is the cause of the magnetic field. However, in any magnet, there is a magnetic current flow, which can be altered to change the poles or remove the magnetism. The magnetic behavior of a material depends on its structure and temperature, and not all metals are capable of being magnetized due to their electron configuration. Phlogiston is not a real substance.

Do electrons continuously flow from north to south pole in magnets. If yes, does this continue to happen when the magnet is attracted or repelled by another magnet or to a ferrite?

A normal magnet like the ones you would stick on a refrigerator do not depend on electric currents to generate their magnetic fields. Instead they use the angular momentum of electrons in their orbitals AND the intrinsic spin of the electrons to generate it. In a non magnetic material the magnetic fields of each atom do not line up with each other, resulting in each field being canceled out by other fields. In a magnet the atoms are aligned so that most of the north poles point one way and most of the soulth poles point the other, each field adding with the other to produce a large noticeable effect.

You are exactly right OP, the flow of the north and south pole magnets causes the magnetic domains to align themselves. The magnet is not the metal itself, it is the substance circulating in the metal.

He is not asking about the north and south pole of the magnetic field, he is asking about the flow of electrons causing the field. Which is incorrect, as there is no net direction of electron flow.

The magnet is not the metal itself, it is the substance circulating in the metal.

Again, incorrect. The electons in the atoms and molecules that make up the magnet are what cause the magnetic fields.

However, in an Electromagnet, which is a wire coiled into mulitple loops, the flow of electrons (current) IS the cause of the magnetic field.

In any magnet there is indeed a magnetic current flow. If it were the metal itself then we would not be able to change the poles or make the material not a magnet anymore.

See here: http://en.wikipedia.org/wiki/Magnetism

Particularly this part of it:

Ordinarily, the enormous number of electrons in a material are arranged such that their magnetic moments (both orbital and intrinsic) cancel out. This is due, to some extent, to electrons combining into pairs with opposite intrinsic magnetic moments as a result of the Pauli exclusion principle (see electron configuration), or combining into filled subshells with zero net orbital motion. In both cases, the electron arrangement is so as to exactly cancel the magnetic moments from each electron. Moreover, even when the electron configuration is such that there are unpaired electrons and/or non-filled subshells, it is often the case that the various electrons in the solid will contribute magnetic moments that point in different, random directions, so that the material will not be magnetic.

However, sometimes — either spontaneously, or owing to an applied external magnetic field — each of the electron magnetic moments will be, on average, lined up. Then the material can produce a net total magnetic field, which can potentially be quite strong.

The magnetic behavior of a material depends on its structure, particularly its electron configuration, for the reasons mentioned above, and also on the temperature. At high temperatures, random thermal motion makes it more difficult for the electrons to maintain alignment.

If magnetism is caused by a substance flowing in a metal, why aren't all metals capable of being magnetized?

In a related note, do you know where I can get some phlogiston cheap?

Your comments are appreciated and understood
 

1. What is electron flow in magnets?

Electron flow in magnets refers to the movement of electrons within a magnetic material, which creates a magnetic field. This flow of electrons is what allows magnets to attract or repel other magnetic materials.

2. How does electron flow create a magnetic field?

When electrons flow through a magnetic material, they align themselves in a specific direction, creating a magnetic moment. This alignment of electrons creates a magnetic field around the material, which can attract or repel other magnetic materials.

3. What is the role of electrons in creating a permanent magnet?

In permanent magnets, the electrons within the material are already aligned in a specific direction. This alignment is maintained even when the magnet is not in the presence of an external magnetic field. This allows the magnet to retain its magnetic properties over time.

4. Can electron flow be controlled in magnets?

Yes, electron flow in magnets can be controlled by applying an external magnetic field. This can alter the alignment of the electrons and therefore change the strength and direction of the magnetic field produced by the magnet.

5. How is electron flow in magnets used in technology?

Electron flow in magnets is used in a variety of technologies such as electric motors, generators, and magnetic storage devices like hard drives. By controlling the flow of electrons, these technologies can produce and utilize magnetic fields for various purposes.
