Question

Is the magnetic dipole moment a vector or a scalar quantity? Write its unit.

Answer 1

The magnetic dipole moment of a magnet is quantity that determine the torque it will experience in an external magnetic field. It is represented by $\overrightarrow{\mu }$

The relationship is given by,

$\overrightarrow{T}=\overrightarrow{\mu }\times \overrightarrow{B}$

Hence magnetic dipole moment is a vector quantity and its unit is $A{m}^2$ or $Nm/T$.
