Oh and I'll share a quote of Heaviside that answers many questions...
"Now in Maxwell's theory there is the potential energy of the displacement produced in the dielectric parts by the electric force, and there is the kinetic or magnetic energy of the magnetic induction due to the magnetic force in all parts of the field, including the conducting parts. They are supposed to be set up by the current in the wire. We reverse this; the current in the wire is set up by the energy transmitted through the medium around it...."
I know it's been said before, but the impact of what that actually means wasn't very apparent until I saw it first hand.
