Certainly, as I corrected myself, if you wave a magnet about fast enough,
say, 1000,000,000 times per second, you will certainly generate an EM wave
and no-one has corrected me on that point because that point is true.

I think your arms would start to ache quite quickly.


Just a tad...

Why would waving a magnet, at ANY speed, do it? I never heard of such. Got to
be a stationary conductor involved too, somewhere very nearby. The speed
would have far less to do with anything than the matching of kinetic energy
into the conductor, and the matching of that to whatever part of that
conductor is an antenna.

A magnet moving on its own reminds me of the question 'what is the sound of
one hand clapping?'
