The magnetic field demonstrator, or magnaprobe, is a small magnet fully suspended in three dimensions in a gimbal mounting. The Magnaprobe can be used to show in three dimensions: Forces between magnetic poles; Induced magnetism; The shapes of magnetic fields between like and unlike poles; Direction of a magnetic field around a bar magnet, a wire or a coil; Properties of a field produced by an electric current. This magnaprobe can be used to clearly show the fields surrounding most laboratory bar magnets, electro magnets etc.
