I've just been given a single rare earth mag conversion for my multiplier. The spool is not magnetic will it work, I have read that the spool does not need to be magnetic as the rotation of the spool causes a reaction and produces a field from the magnet. Is this true??????? (Its an aluminium spool.) The kit fits perfectly on the endplate and winds in and out really well, but will it work?????? Anyone with any advice, I'd be really grateful. Cheers Rich.
