Hello. I'm looking to build a strong electro magnet with ac power. I was going to use a MOT transformer so the primary was going to be the same windings. For the secondary windings though I'm trying to decide if I want to go with a higher current or voltage. I would assume that a stronger current would produce a stronger magnetic field. Any good ideas? Im going to be using the electromagnet to induce eddies current in aluminum to repel it (some background info if it helps). Thanks for any info,suggestions, and help, Zig.
