How come a magnet attracts plastic particles?

• dmos62 6y ago
  To answer my own question. It's vegetable oil mixed with magnetic powder. It's the oil that attracts plastic, but it's the magnetic powder that let's you collect it with a magnet.

  As I understand it, he 'glues' metal to the plastic. The magnet picks up the metal, and the glued-on plastic comes along for the ride. Now anyone with basic chemical knowledge will probably shoot me for abusing the word glued like this, so feel free to correct.
