Magnetism Revealed!!

A trusted advisor in the realm of physics, electromagnetic transduction and spiritual electroacoustics tells me that I'm tragically misinformed about magnetism.  Thanks to Albert Einstein and his Theory of Relativity, we (well not "we" as in 'us' but "we Physicists") know exactly what magnetism.  It goes like this:

"Magnetism is the wake of the electric field as it moves through space at the speed of light" .

Right?  Could a fooled me!  And so, doesn't this all make sense now?  Aren't you all more comfy with this "mysterious" energy source; magnetism.  I know I am.  It's as tangible for me now as a Big Mac.  Don't you think?
