Does accelerating magnet emit radiation? Just like accelerating charge produces emits radiation, does an accelerating magnet emit electromagnetic radiation?
 A: This is only a partial answer, but since there has been no other answer in the last 24 hours I will post in the hope it is helpful.
We know an accelerated charge produces electromagnetic radiation because that's how radio transmitters work. So if you wave an eletric charge around it will radiate. Similarly, if you wave a magnetic charge around it would radiate.
The problem is that a magnetic charge would be a magnetic monopole and as far as we know these do not exist. The magnets we all played with as children are magnetic dipoles not magnetic charges. So the question is whether a magnetic dipole radiates when you wave it around.
And this is where we run into problems because the answer to this apparently simple question seems obscure. I have posted a question Does an accelerating electric dipole radiate? to ask this question, but at the time of writing there is no answer to it.
A: In classical electrodynamics any changing charge or current distribution is accompanied by radiation.
Antennas are required to make the emission of radiation efficient.
