The orientationof dipole should be antiparallelto the magnetic field B. In that orientation, U^max = m B.

What should be the orientation of a magnetic dipole in a uniform magnetic field so that its potential energy is maximum?
Share
The potential energy of a magnetic dipole is maximum when it is oriented opposite to the magnetic field. In this position, the angle between the magnetic moment and the field is 180°, resulting in maximum potential energy.
