spazzyone Posted August 15, 2006 Report Share Posted August 15, 2006 I have two questions 1. how can i tell the north/south side of a magnet? 2. can i cut a magnet with out hurting the magnet itself? im trying to make a split coil driver for a sustainer ala PSW's thread ive made two mini bobbins that when put together fit a single coil cover and i have a bunch of magnets that are 1/4" x 1/4" x 2 1/4" and i want to cut one in half but will cutting it affect its strength. i plan on using a dremmel and a cut off wheel i know it can chip or shatter but i think the cutoff wheel will prevent this any help would be great Quote Link to comment Share on other sites More sharing options...
ihocky2 Posted August 15, 2006 Report Share Posted August 15, 2006 I can't speak towards the effects of cutting a magnet, but determining the polarity is fairly simple. You just need another magnet that has the poles marked on it. When they push appart, you have like poles, so you know which one you'r dealing with. Stewmac sells a cheap tool that indicates the polarity of a magnet as well. Quote Link to comment Share on other sites More sharing options...
