Eddy Current / LenzS Law Set

Product Description

This kit consists of two tubes (made from copper and plastic, each about 250mm long) and two discs (a supermagnet and an aluminium disc of a similar size). When the supermagnet is dropped down the copper tube, it falls much more slowly than might be expected. The other tube/disc combinations do not show this effect, since eddy currents are only produced using the copper tube and the supermagnet.
