>concise description of how relativistic effects tie electrical forces to magnetic ones

The answers you seek require some pre-requisite knowledge you don't have. You need to know basic physics, basic Electromagnetics and then a good understanding of special relativity.

I can refer you too books, but that is all. If you want to understand how shit works, you need to take the time to study.

>associated with negative charge instead of any charge

This is not true, you can associate however the fuck you want, as long as your system is consistant. You could call plus minus, or minus plus, it doesn't actually fucking matter.

>why the spinning of said charged particle creates such a strong directional force

That is not true. When they talk about "spin", it is a Quantum mechanics term. It doens't mean a "physical spin". Spin just means an intrinstic angular mometum. Again, you need an understanding of basic physics, before you can even begin to understand what they mean in quantum physics.

>What is the laser illuminating itself against to appear so solid?

Photons (light), do not a medium to travel thorugh. They can/do travel through empty vacuum. Chapter 6, in this book explains it very well.

Lol.....the forces (E and M) are the same strength, it is all a matter of perspective, and how you set up your system.

It is pretty obvious that you need to study a little more special relaitivity, if you dont even know how to apply that shit to fields, but you seem to be on the right track though.

Do you remember how that the magnetic field is only created with moving charge? Never wonder why? And since motion is relative, what would happen if I was moving with the electron, then there would be no magnetic field!....wtf?...Yeah, that turns out to be correct, the Electric and magnetic field are not some "set fields in space", they are in fact "frame dependent".

We usually see magnetic fields, because the electrons are usaully moving (leading to relativistic effects), but if you stop the electron the magnetic fields will all dissapear!

All that shit is explained in basic EM, or Classical Field theory. pic related

Magnetic permability is just a product of the medium the magnetic field is propagating in, again since the magnetic field is just the relativtisc effect of the em field, it can be directly related to the electric permability, and visa versa. Which is in turn directly related to the speed of light. Hence there is only one fundemental property of the medium (the speed of light (the photon)), you can the find the electric and magentic permability from it, and the way you set up your system.

Make sense? anything else?
