I too have been assured by people who have tried it that it works but was
sceptical.  I have an Ortofon MC3000 so I wrote to Ortofon to ask their
opinion.  I felt that as silver (the coil material for the MC3000) or
copper (what many others would have) and the body of my cartridge (ceramic)
are non-ferrous materials it was unlikely that they could become magnetised
(the implied problem).  Ortofon agreed and said demagnetisation made no
difference as there was nothing to demagnetise.
