Q123 / 180 · NEET 2013 (All India) · Physics

A current loop in a magnetic field

  • A
    experiences a torque whether the field is uniform or non-uniform in all orientations
  • B
    can be in equilibrium in one orientations
  • C
    can be equilibrium in wo orientations, both the equilibrium states are unstable
  • Correct answer
    D
    can be in equilibrium in two orientations, one stable while the other is unstable

Solution

For parallel $\mathbf{M}$ is stable and for antiparallel is unstable.

Hence, the correct answer is option: 'D'.
