Purpose:Demonstrate the force on a current-carrying wire in a magnetic field.
Description:A wire is placed or held between the poles of a small horseshoe magnet. When the ends of the wire are connected to a 6-volt battery, the wire jumps out of the magnet. The current in the wire or the orientation of the magnet can be changed to investigate the directions of the vectors involved.
See K1-03 for a larger version of this demonstration suited to large classrooms.
