Try putting the permanent magnet in a vise grip, and secure it really good! You can do this the poor man's way: get a crapload of magnet wire from radio shack and wrap a LOT of turns around a stick of rebar. Be warned, this is a one time use electromagnet. 'Aquire' as many car batteries as you can, and get a heavy duty switch. The switch will also die from this. Connect all the car batteries you can in parallel, or best yet use two banks so you have 24V. Use a really long stick, or something not conductive, to flip the switch to connect the circuit. Circuit being the car battery bank and the wire wrapped stick of rebar. You will get one hell of a field! Unfortunantly, the whole thing will melt and there will be a dead short. You can put limiting resistors (think many megaohm power resistors) to limit current but you'll get less punch if you do this. Could also save your parts from destruction. If the resistors melt, you didn't have enough and you're probably screwed. Figure 500-600 cold cranking amps PER car battery. Beware the batteries exploding. Its rare, but it has happened before. It really sucks, trust me.
