On: What Materials Are Magnetic?

Not a physicist, but I’d guess that bending the metal causes it to heat up, which in turn could make it easier for electrons to align and respond to magnetic waves.

Nope, heating would make it non-magnetic again.

It's the act of physically working it that makes it change structure.

you're only right about not being a physicist. sorry, had to have a laugh. What made you draw that conclusion?
