Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational acceleration and any other accelerations. floating ring magnet set is used for demonstrating magnetic repulsion. The set has five magnets that are placed on a rod tor observe the magnetic repelling or “floating” effect. The magnets are Plastic Coated for resistance to abrasion, and have a 32 mm external diameter.
