- In a magnet or magnetic body, one of the two regions where the magnetic lines of force converge, and hence magnetic intensity is at a maximum. The other region is the south pole (3). Such a pole, when part of a magnet which is freely suspended, will seek a south pole, as opposite poles attract. Also called positive pole (1).
