Does waving a magnet back and fourth produce an EM wave?

AI Thread Summary
Waving a permanent magnet back and forth does produce an electromagnetic wave. The frequency of the wave corresponds to the rate at which the magnet is moved. However, the amplitude of the generated wave is extremely low, making it challenging to detect. It is theoretically possible to detect this wave using a radio if external noise is minimized. Overall, while the phenomenon occurs, practical detection remains difficult due to the low amplitude.

If you take a permanent magnet and wave it back and fourth, or even just move it along in one direction, this seems like it should create an electromagnetic wave.

If so, how would one compute the frequency, and could you possibly detect it with a radio if you shielded it from other noise?

It does, it's frequency is the frequency that you are waving at it, and the amplitude is so low as to render detection very difficult.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
