Question

A magnetic dipole in a uniform magnetic field has: (Take zero potential energy when magnetic dipole is perpendicular to magnetic field), Maximum potential energy when the torque is maximum, Zero potential energy when the torque is maximum, Zero potential energy when the torque is minimum, Minimum potential energy when the torque is maximum

MARKS App · Accepted Answer

Torque, τ = M B sin θ and potential energy, U = - M B cos θ τ is maximum when θ = 90 o U = - M B cos 90 o = 0 .
