Problem 38P
Figure shows two square current loops. The loops are far apart and do not interact with each other.
a. Use force diagrams to show that both loops are in equilibrium, having a net force of zero and no torque.
b. One of the loop positions is stable. That is, the forces will return it to equilibrium if it is rotated slightly. The other position is unstable, like an upside-down pendulum: If rotated slightly, it will not return to the position shown. Which is which? Explain.
