As I recall, it has a very narrow body when viewed on end. Perhaps this is the reason its magnetic field is so evident when you bring ferrous materials near it. But I guarantee you it's normal and/or perhaps exaggerated by a magnetized coil. Why not carefully demag it and see what happens? (I would consult the importer, Robin Wyatt, I think, before going ahead with that.) However, generally a magnetized coil adds only a tiny bit to the field generated by the permanent magnet that makes the thing work as a transducer.
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.
