Re-magnetize after coating?
Is there a reason re-magnetizing a magnet after coating has not been considered? I know one of the main issues with TiN and similar coatings is that the coating process requires heat and that degrades the magnetic force. Neodymium magnets can be re-magnetized with another powerful magnet. Its my understanding that this requires a high powered industrial strength electromagnet and would not be practical on a DIY or home scale, but surely we could convince a magnet manufacturer to re-magnetize some coated magnets for us.
