Invert the apparatus and observe magnets simultaneously sliding down three different rods! The velocity is inversely related to the conductivity of the materials: copper, aluminum, and rigid plastic. A recreation of an old, hand-made apparatus found in a university physics storeroom, this is great for demonstrating Lenz's Law! 21.6 x 28 x 1.9 cm (8.5 x 11 x 0.75 inches)
