Can a MC cartridge be damaged by a magnetic screwdriver?

[zyss]

A screwdriver, being magnetic, touched a MC cartrigde and attracted it for a moment. Could this theoretically alter the performance of the longevity of the cartridge? Generally, does it make sense to keep MC cartridge far from possible magnets? How is it with direct drive motors? Do they interact with magnets of MC cartridges worsening their performance? I had an experience with a cartridge literally jumping on a record in one specific location (on any record at the same location), and the manufacturer explained that by reference to exceptionally strong magnetic field coming from the direct drive. This cartridge had a strong magnet also. I changed to another cartridge by the same manufacturer and there was no jumping.

Hi

I don't think so, but with one big exception. It's really easy for the screwdriver to be dragged towards the stylus and ruin it! For that reason, it's wise to be very careful with screwdrivers (or hex keys) anywhere near an MC cartridge. Mine (an Ortofon Rondo) has threaded holes for the bolts, so they are tightened from above - much safer.

Apart from the reply above, also be aware that some versions of the Shure SFG use a steel beam...these are inappropriate for mc carts.

I'm curious to know which dd was causing the issue?
