About this item:
A great device for teaching Fleming's left-hand rule, this demonstrator consists of a base with two separate parallel conductors, a large U-shaped magnet that fits between the parallel conductors, and a conducting rod attached to a plastic disc. When a current is passed through the rods, a force is exerted on the rod with the disc which causes it to roll along the parallel rods. Includes activity guide.
