Reading this talk. Mind blown. It explains how the concepts of special relativity and length contraction between inertial reference frames converts magnetic forces to electrostatic forces depending on your frame of reference.
I am inclined to believe, after reading this, that there really is no magnetic force at all, only an electrostatic force. What we call a magnetic force is nothing more than an illusion, a consequence of special relativity as charged particles are moving at near speed of light relative to other charged particles. Am I correct in this conclusion? Permanent magnets are essentially alligned magnetic moments of individual atoms with aligned unpaired valance electron spin (I think I explained that right) so their fields should be also be explained using quantum and special relativity theories.
I wonder though, if the magnetic force/field isn't really there at all, then why the search for magnetic monopoles? Also, is magnetic permeability then just how the charged particles of the material aid or hinder alignment to the magnetic moment?
