The alternating current will demagnetize it. John M. Ross Windsor, Nova Scotia, Canada jrpiano@win.eastlink.ca ----- Original Message ----- From: Christopher Purdy To: College and University Technicians Sent: Wednesday, January 11, 2006 4:46 PM Subject: [CAUT] magnetized screwdriver This is a bit off topic but an interesting question about tools. I recently have found a couple of my screwdrivers had voluntarily become magnetized somehow. I couldn't figure out why but my student says that dropping the tool can do it somehow. He can't defend his theory but says that either denting or the impact realigns the polarity somehow. Is this true? Can someone confirm or deny this and explain how in terms a dummy like me can understand? If this is true, is it possible to de-magnetize something? How would you do it, drop it again? How do you undrop something? Chris Christopher D. Purdy R.P.T. School of Music, Ohio University Rm. 311, Robt.
