Scrap heap magnets are basically electromagnets. Electromagnets

are simply wire coils usually would around an iron core. When

connected to a DC voltage or current source, the electromagnet

becomes energized, creating a magnetic field just like a permanent

magnet. The magnetic flux density is proportional to the magnitude

of the current flowing in the wire of the electromagnet.
