If $\vec M$ is the magnetic moment and $\vec B$ is the magnetic field, then the torque is given by |
$\vec M.\vec B$ $\frac{|\vec M|}{|\vec B|}$ $\vec M×\vec B$ $\frac{|\vec B|}{|\vec M|}$ |
$\vec M×\vec B$ |
The correct answer is Option (3) → $\vec M×\vec B$ The torque on a magnetic dipole in a uniform magnetic field is $ \vec{\tau} = \vec{M} \times \vec{B} $ |
