U=- overset arrow M⋅ overset arrow B=-MBcosθ

Q. A current carrying loop is placed in a uniform magnetic field in four different orientations ; $I, II, III$ and $I V,$ arrange them in the decreasing order of potential energy:

$I > III > II > I V$

$I > II > III > I V$

$I > I V > II > III$

$II > I V > I > II$

$U = - M \to \cdot B \to = - MB cos θ$
