cartridge demagnetization

Are there any telltale signs that your phono cartridge [especially MC] needs to be demagnetized, or is this just a preventative maintenance issue?

I think you mean "soft magnetic" instead of paramagnetic. dave

I was looking for a word that described the properties of "soft" material but turns out paramagnetic wasn't it ;^) Cheers,
