How would you be able to know if it is "abnormally magnetized". As others have said, it contains a tiny but very powerful magnet or maybe a pair of magnets, by definition. These produce a field that pervades the structure and evidently extends outside the confines of the body. This is not at all unusual. My Ortofon MC2000 will grab a screwdriver right out of my hands (and crush its own cantilever, if I'm not careful.) Could the coil have become magnetized, due to its proximity to the magnet(s)? (That's the magnetic field we try to get rid of when we demag an MC.) Yes, but the magnitude of that field would be tiny and not externally detectable, in my opinion. If you're still concerned, ask the importer.
Miyajima Magnetism
I bought a used Miyajima Spirit MC Mono cartridge for playing 78 rpm records last year. It works OK but it is heavily magnetized. I noticed it right away when I tried to do set up and it pulled my screwdriver really hard against the side of the body. The body is made from brass and plastic which are not magnetic so it is not the casing material that is the problem. It sounds fine but I have the feeling it would sound better if the charge was removed.
Any idea of how to safely demagnetize the thing? I see cartridge demagnetizers online but I am not sure they would solve this problem.
