Whether they're sorting out scrap metal or helping us unlock the secrets of the universe, electromagnets are pretty nifty devices. What's so great about magnetism on demand? We'll electrify you with the details.
Four main factors affect the strength of an electromagnet: the loop count, the current, the wire size, and the presence of an iron core.
