Many types of magnets are used in data storage where the magnets are coated with an organic coating (paint) to encapsulate the magnetic particles. An inspection is needed to determine whether the coated magnet surfaces are free of magnetic or magnetizable particles. The presence of such particles could cause erasure of information in addition to mechanical damage.
