Question
When does a magnetic dipole possess maximum potential energy inside a magnetic field?
✓

Answer

  1. Magnetic moment and magnetic field are antiparallel.
Explanation:
A magnetic dipole possess maximum potential energy when its magnetic moment and the magnetic field are antiparallel. When the magnetic dipole is aligned along the magnetic field, i.e. when $θ = 180^\circ,$ it is in unstable equilibrium having maximum potential energy.
