Why is there Magnetism?
... Conclusion • An example was given to show that, at least in one case, the effects of a magnetic field on a moving charge may be completely described as the effects of an electric field on that same charge in its rest frame • This is a general truth: magnetic effects are merely electric effects in a ...
