Affordable, Easy, Fun
Present these demonstrations in front of your class to excite your students about learning core physics concepts. Set up and execution are simple, so you can spend more time engaging your students. Ideal for introducing a unit or using as reinforcement after a lesson, these demos are available for all fundamental physical science topics.
Track the speed of a Neodymium magnetic ring as it races vertically down the outside of three 12" rods. Made of copper, aluminum, or PVC these rods are not magnetic, however each of the two metal rods create an induced magnetic force, affecting the resistance of the metal ring and the rate that it falls. When dropped down the PVC rod, the ring is unimpeded, allowing students to see a controlled point of comparison. This hands-on and exciting demonstration allows greater visibility than traditional Eddy Current tubes, as the ring drops down the outside, rather than inside the tube. For a varied application, try placing the rods in a freezer for at least one hour before performing the demonstration again. Students will see that the temperature change causes the ring to fall about 18 to 27 percent slower.
Kit includes a wooden base, PVC, copper, and aluminum rods, two neodymium magnets, and a detailed demonstration guide.
