A small current loop is placed near the end of a large magnet as shown.
1. Draw vectors to show the magnetic force on each side of the loop.
What is the net effect of the magnetic forces exerted on the loop?
2. Suppose that the loop were to rotate until oriented as shown.
Now, what is the net effect of the magnetic forces exerted on the loop?
Is there an orientation for which there is no net torque on the loop? Draw a diagram toillustrate your answer.
3. Are your results above consistent with regarding the current loop as a small magnet?
Label the poles of the current loop in the diagrams above and check your answer.
