I had a hv that seperated a magnet, it was not smooth either and its similar to the pletty, but not as many plates near the rotor and it also has the hard spots as does the pletty(though not as hard to turn). if the magnet has come loose it must have split for the shaft to roll free. If the magnet did not split and seperate, I'll have to agree with squee on it demagnetizing
