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 para llel 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. Shipping weight: 2 lbs, dimensions: 9.5" x 6" x 3.5". Show more
