The Magnetic Pole Finder is a quick and easy way to demonstrate the 3-dimensional magnetic force field. It consists of a small alnico bar magnet mounted on a gimbal so that it will rotate freely. It is more convenient and accurate than the traditional methods using compasses and iron filings. The Magnetic Pole Finder is perfect for experiments on the forces between magnetic poles, fields around wire and coils and the properties of fields produced by electric currents.
