I need to make an electromagnet and i have no copper,anyone know where i could get copper around the house? i need to get this done ASAP.
It would be a difficult task, but you could very carefully disassemble and unwind an old junk electric motor. Usually, the varnish that they bake into the windings on the motor stator makes it nearly impossible to unwind it, without destroying the varnish insulation. Sometimes light duty fan motors and such (with shaded-pole motors) aren't too heavily varnished, but the wire gauge/size will be light. A transformer would also have copper windings, but getting the laminations apart is usually pretty difficult. The generator/magneto coil from an old motorcycle engine might have some recoverable copper. An old doorbell, with the solenoid that hits the chime bar would have a copper solenoid winding in it. Good luck!
