Question

What is the magnetic moment of a bar magnet?

Answer 1

Magnetic moment:

1. A vector that connects the object's alignment torque from an independently applied magnetic field towards the field vector on its own is called a magnetic moment.
2. It is a vector quantity.

Mathematically, this can be represented as:

$\mathrm{\tau }=\mathrm{\mu }\times \mathrm{B}$

$\mathrm{\tau }$ is the torque.

B is the external magnetic field.

$\mathrm{\mu }$ is the magnetic moment
