The uniqueness of a magnet? Let me tell you why.


Quote by sophiecentaur View Post
I understand your amazement but are the magnets any more 'significant' than the cables being strong enough hold them - except that you don't see magnets every day?
There is a story that, when asked which was the greater, the Sun or the Moon, a Greek philosopher said that the Moon was far greater because it shone at night, when it was dark. The Sun was far less impressive because it shone in the day, when it was light anyway.
Familiarity can breed contempt.

sophiecentaur do you realize "magnets" are probably the only known material to repel and attract its own(Of my own knowledge). No cable( without electricity) can do that, and no wall plug can do that too! Plus that is a long lasting effect that stays easily for 50 years and more depending on the material and state.

No magnet can work without electric charges inside either.
The parts in wall plugs (and everything else solid) attract and repel each other, otherwise those objects would evaporate immediately.

There is a difference you can't see the electric charges and seperation when you look at a solid object unless you use something like an electron microscope.Where as a magnet attracts and repels with an apparent unseen force through all materials with a macroscopic force.You have to wonder how and why does it do that.

Is this the reason why if you wan't to send a spaceship to explore the Sun you should go at night.

And when you say that it has no energy, in fact it does(potential energy).
Who says that?

Btw, your reasons why magnets are unique pretty much all apply to gravity also.

Go team magnet! I'm a fan of gravity but a magnet toke my heart first!

Another good point. And add to that I'd like to say electrical forces are always there... present.
You can't find a material that has a invisible strong force present besides its electrical force.

I personally think ALL forces of nature are equally mind blowing. You can't really say one stands out more than another. They're all significant and amazing.

Surprised nobody has referenced the interview where Feynman was asked about the behavior of magnets... he gets right into the magnet part after about four minutes.

Oh, Miyz, if you really, really like magnets, take a look at this...

My point is that your thread title is about the uniqueness of magnetism, but nothing you mentioned is unique. At least not anything other than your personal affection.

We know a strong invisible force is present. That we can all agree 100%(There are other theories but I'm not sure of their "reality").
Right. The force is there, and the "force there" (more precisely, force area or zone) is the original meaning of "force field", abbreviated to "field". That's very objective. Models of "what really is happening there" are speculation.

When you bring to of those objects and look at them, CLEARLY a magnet has the full capability to attract any metal/magnet near by and applying force BY its own(forget the point of "you" putting the magnet/metal there) It also repels by its own, now how can you compare it to a spring? A spring on the other hand stays there doing nothing... ONLY when you apply force to it directly and leave it be... It acts by its own. but only then you'd find an act from the spring! However, again I remind you that a magnet has a force of its own mind you, why can't aren't we amazed significantly at this feature?

And when you say that it has no energy, in fact it does(potential energy). It attracts/repels a magnet, that is force applied to a magnet within a distance = W = Fd , and when attracted by a magnet or repeled or even attracts a metal, let me remind you of its "potential" state converted into "kinetic". (Simplest way to describe it without going into detail.)


Im a man fascinated by electromagnetism specifically: Magnets, and their wonderful feature of having a force packed inside that some of them can lift 10x or 100x or 1000x of its own weight. HOW REMARKABLE IS THAT!
Miyz,
A few things:

1. Magnets totally rule.

2. MAGNETIC FORCES DO NO WORK. I'm not sure if this was a point of confusion for you, but I had to throw it out there, cause it cracks me up.

3. Your comparison of a spring which apparently does nothing, and a magnet which miraculously attacts/repels other magnets, merits a response. It seems like what's really astounding you is the action at a distance thing. If I drop a spring into a tight gap between two slanted walls, so that the ends are close normal to the walls, it will exert a force on the walls. If you drop a magnet near other magnets, it does attract/repel them. Not so different now, huh. Give springs some cred.

Yea forgive me while writing that down forgot a debate I had earlier in another post. I meant generally magnet have a potential energy that tend to attract magnets and metals. Now interms of the magnetic force doing work... After a long long discussion I agreed its due to the change in B it induced electrical fields that interms does all the work.
