If I understand this well, then the rotating permanent magnet would generate waves. would it? If yes would they be ordinary EM waves?
As MackBlanch says, yes. The funemental frequency would be the rotational frequency of the magnet. DaveC's ripples are spiraling ripples. Since we know that the alternating magnetic fields point (mostly) in the circumferal directions, the alternating electric field would be parallel with the axis of rotation.
