Question

Physics: Acoil with a magnetic moment of 1.50 a-m^2 is oriented initially with its magnetic moment antiparallel? to a uniform magnetic field of magnitude 0.815 t. what is the change in potential energy of the coil when it is rotated 180 degrees so that its magnetic moment is parallel to the field?

The electrostatic forces between two charged objects ... (as well as the gravitational forces between two masses) ... are equal in magnitude but opposite in direction. (choice-C)

This is exactly what we would expect from Newton's third law of motion.
