Exercise 27.49

A coil with a magnetic moment of 1.43A?m2 is oriented initially with its magnetic moment antiparallel to a uniform magnetic field of magnitude 0.825T .

Part A

What is the change in potential energy of the coil when it is rotated 180 ? so that its magnetic moment is parallel to the field?
