Working Title: Selective Magnetism: From YKTTW
Daibhid C: Not A Subversion. (Not totally sure they're aversions either, but I'll let someone else judge how accurate they are).
- Subverted in the Ed Edd N Eddy episode "Hands Across Ed". When the Eds activate an enormous electromagnet, hoping to use it to steal quarters, it immediately drags practically every metal item in range of them. At the end of the episode, they try using the magnet again to disrupt Rolf and Kevin's show, only for it to pull them directly to a dumpster.
- Subverted in the Teenage Mutant Ninja Turtles cartoon. Donatello attempts to use an electromagnet at a junkyard to "pluck a sword out of Shredder's hand". Shredder laughs at this plan and announces that sword is made of an alien metal and that magnets only work on steel. When Donatello turns the magnet on, Shredder's steel armor is attracted to it, causing him to fly toward the magnet and drop the sword.
- "only four metals are ferromagnetic: iron, nickel, cobalt and neodymium" Neodymium is not ferromagnetic. Neodymium rare-earth magnets use an alloy of neodymium with iron and boron which is. Gadolinium and dysprosium are ferromagnetic, however, as are numerous metallic alloys. The same goes for samarium rare-earth magnets...samarium itself has paramagnetic ordering like neodymium does, it is the alloy with cobalt that is useful for magnets.
