In a bar
magnet the poles of the magnet are situated a little distance inside the ends
of the magnet. The distance between these two poles (north and south) is known
as magnetic length. The actual length or the size of the magnet is called the
geometric length. And therefore magnetic length is obviously slightly lesser
than the geometric length. magnetic length is 0. 85 times of the geometrical length of any
magnet.
