2 pole rotors are easy to be re-magnetized but to my knowledge 4 pole rotors like CC-Neu are pre-magged before assembly, they are much harder if possible to be re-magnetized. The fiber wrap adds up the difficulty.

as far as i know these neodynium magnet rotors cannot be re-zapped.
i belive the older style rotors used an iorn core type magnet. and to re mag them involved placing them inside a huge electro magnet and turning it on, super high current for a few seconds.
