If M is magnetic moment and B is magnetic field, then the torque is given by |
$\vec M.\vec B$ $\vec M×\vec B$ $\vec B×\vec M$ $\frac{|\vec M|}{|\vec B|}$ |
$\vec M×\vec B$ |
The correct answer is Option (2) → $\vec M×\vec B$ The torque on a magnetic dipole in a uniform magnetic field is given by: $\tau = \vec{M} \times \vec{B}$ Magnitude: $|\tau| = MB \sin\theta$ |
