Question

What is the relation between pole strength and magnetic moment?

Answer 1

Relation between pole strength and magnetic moment:

1. The pole strength of a magnet is defined as the force with which materials are attracted to the magnet. It is denoted by the letter $\mathrm{m}$ and is a scalar quantity.
2. The magnetic moment is the product of the magnet's pole strength and length. It is represented by the letter “M”.
3. Magneti moment can be written as $\mathrm{M}=\mathrm{ml}$, Here, $\mathrm{l}$ is the length of the magnet.
