Parallel to the direction of magnetic field B (i.e., θ = 0°). In that orientation, U^min = – m B.

What should be the orientation of a magnetic dipole in a uniform field so that its potential energy is minimum (or the dipole is in stable equilibrium)?
Share
The potential energy of a magnetic dipole in a uniform magnetic field is minimum (stable equilibrium) when the dipole aligns parallel to the field, with its magnetic moment (m) pointing in the same direction as the field (B).
