Frey Scientific Laplace's Law Demonstrator with included teacher's guide is used to teach Fleming's left hand rule. It comes with 2 separate parallel conductors, a large U-shaped magnet that fits between the parallel conductors and a conducting rod attached to a plastic disc. When conducting rods are supplied with current, a force is created on the rod with the disc which makes it to roll along the parallel rods.
