a simple one.get two wires preferrably copper rubber coated ones and a 9 volt battery wrap both the wires around a nail leaving enough of each to reach the battery.touch the end of one wire to the positive end and the other to the negative and the nail is charged. you'll be picking up paperclips in no time

When the need arises, I wrap a wire around my screw driver and run power through it. Walla, the tip is magnetized again and holds the screw on it.

Why make one? Take the coil out of an old car.
