eletromagnetic induction occurs via electromagentic waves...light is the visible portion
of these many common inductions, like those of small coils at 60Hz, the speed of propagation...that is, the speed of light..... is immaterial...but at ultrahi frequencies and large coils or large coil separation, such time delay of propagation may have to be taken
into account.
all this is what mfb is taking about.
