These Neodymium rings are identical in size and shape to our F2516 ring magnets. They can be used with the F2516 ring magnets to demonstrate how the intriguing 'eddy currents' produced by a magnet and copper pipe create a damping effect. A non-magnetic ring will slide down a length of copper pipe in an instant but the magnetised variation will descend slowly. A great way to bring magnets to life in the classroom.
