A circular coil of wire with dipole moment 7 is placed in a uniform magnetic field so that the field lines are В parallel to the axis of the circle. If the direction of current in the wire is reversed, what is the magnitude of the change in the coil's stored energy? O 2 µB µB O 0.866 µB 0.693 µB There is no change in the stored energy.
