PURPOSE: Demonstration of field lines using magnetized wires.

DESCRIPTION: A bar magnet is placed on top of the wire array, and the wires become magnetized and line up along the magnetic field lines.

SUGGESTIONS: This one is good to take on a road trip to illustrate very graphically the nature of the magnetic field lines of a bar magnet.
