Question

State the relation between magnetic length and geometric length of a magnet. Also State the relation between magnetic field due to a bar magnet at a point along its axis and equator.​

Answer 1

Explanation:

Magnetic Length: The distance between the two magnetic poles is called the magnetic length. ... A bar magnet consist of two equal and opposite magnetic pole separated by a small distance.

AND

Geometric length: Geometric length is the measure of total length of magnet. A bar magnet consist of two equal and opposite magnetic pole separated by a small distance. Poles are not exactly at the ends. The shortest distance between two poles is called effective length and is less than its geometric length.
