A current loop in a magnetic field

Options

  1. Aexperiences a torque whether the field is uniform or non-uniform in all orientations
  2. Bcan be in equilibrium in one orientations
  3. Ccan be equilibrium in wo orientations, both the equilibrium states are unstable
  4. Dcan be in equilibrium in two orientations, one stable while the other is unstable

Correct answer

D. can be in equilibrium in two orientations, one stable while the other is unstable

Step-by-step solution

For parallel M is stable and for antiparallel is unstable.
