A Lenz' Law demonstration device. The invention is a child's educational toythatdemonstrates magnetics, Lenz' Law (which creates a current within the tube bycreating amagnetic field that opposes the field of the falling magnetic - making themagnet fall moreslowly as opposed to a nonmagnetic drop that would fall at the speed ofgravity). A magnet isdropped into a larger diameter copper (or other ferromagnetic material) tube.The magneticresistance then causes the magnet to drop at a slower speed in the tubetherefore creating theappearance of anti-gravity and generating an electrical charge through theresistance.
