Tstair_11 Posted August 24, 2016 Share Posted August 24, 2016 Just earlier I was playing with a sewing needle and heating it up in the flames of a candle. When I set it down on the glass lid of the jar, it spun around quickly in the opposite direction. I noticed the point of the needle was facing north. Can anyone explain how this works?

If it works as a compass though, you definitely managed to magnetize it. https://en.wikipedia.org/wiki/Thermoremanent_magnetization Edited August 24, 2016 by Endy0816 Link to comment Share on other sites More sharing options...
