I am looking at electromagnets and discovered an article using an A/C version. What I am surprised by is that there is no mention of how the A/C is being used. http://www.coolmagnetman.com/magacem.htm Wouldn't someone creating this version of an electromagnet kill themselves? There's no mention whether the author uses any kind of lamp or anything to control the power running into this thing. If this thing was wired into an outlet, wouldn't a fuse at the main's blow?
