Question

The relation between geometrical length (Lg) of a magnet and its magnetic length (Lm) is...

Answer 1

The relation between magnetic length of a magnet and geometric length of a magnet is that, magnetic length is 5/6th of the geometric length.

1) The magnetic length signifies the distance between the poles present in the magnet.

2) In a bar magnet the poles are considered to be situated at a point slightly away from the two side of a bar magnet.

3) So, the magnetic length is slightly less than that of the geometric length.

4) Geometric length is the actual length of a bar magnet.

5) Magnetic length = 5/6 * Geometric length
