Haha, wrinkle that brain!
The two simplest ways to make a Magnet are Iron + Lightning and Wire + Iron.
We've got a big update coming tomorrow or the day after and these are the recipes we have for the coming version (v0.10.1), but I'm not certain they're in the version you're playing (v0.9.1). Give us a couple days though and we'll have lots of new stuff :)
Thanks so much for your kind comments, we love to hear that people are enjoying our games. Cheers!
