Hi... I have been all over Wikipedia and various other websites that attempt to explain the nature of magnetism, and I just get more and more confused.
I have seen Maxwell's equations, and that explains "what" and "how much" but doesn't explain "how" or "why".
I have heard mention of "virtual photons" and "lines of force" and all that stuff.
Still, I don't feel that I really understand how a moving electron causes a magnetic field.
I am ready to accept that some things can be observed but not explained, but I still am trying with this one.
If anyone can help me out, maybe this forum will be the place where I finally understand.
Some questions:
1. If an electron is moving through space, and if you are looking at it going away from you, is there anything special about clockwise versus counterclockwise? I mean, is there anything actually going that direction or is it only a matter of convention for us humans, so we get our signs correct and predict the right outcomes? Same for the "right hand rule" and "right hand grasping rule" and those silly things. Do they really mean anything?
2. If the answer of #1 is "yes" then is there only one kind of electron or two kinds? Like, is there a "left hand spinning" and "right hand spinning" electron in the universe? I know that quarks come in many flavors, but do electrons?
3. If electrons are moving in a copper wire, then they are not really moving in a straight line -- they are swinging all around the atoms of copper, but they are all *generally* moving in the same direction. Does the magnetic field really depend on this average motion?
4. What "carries" magnetic field or is it more like gravity, where it's sort of bending space-time fabric? And how is a magnetic field related to electric charge in the axis of time? Because a magnetic field comes from a "changing" (moving) electric charge and vice versa.
Maybe someone will have the key to make me understand this topic. I can use inductors but I don't understand what is *really* going on.
Thanks for your wisdom, in advance.
