[tniptkkv] Moving a magnet

Does moving, or accelerating, a permanent magnet release electromagnetic radiation?

A moving magnet can produce electric current along a nearby wire, and moving charges in the wire produce electromagnetic radiation.  But they might cancel somehow.

Perhaps magnet plus pendulum.  Pendulum probably needs to be forced to compensate for the energy lost to radiation.
