Is that cost efficient?

Thank you for the quick response. I wish the answer were different though. In a nut shell, if I had a battery powered electromagnet it wouldn't be magnetic for long because it would require too much electricity to keep it "on" right?

Magnets "on and off" Is there an easy and cost efficient way to "turn on and off a magnet"? Is it possible? I have a 6x9 speaker magnet (6x9 an old 80's style car speaker), the magnet itself is about the size of a hockey puck and I want to be able to "push a button" so I can remove anything...
