Chapter 8.1, Problem 2bT

To understand the interaction between the wire loops and solenoids in section I. we can use the idea that a force is exerted on a charged particle moving in a magnetic field. In each of those cases there was an induced current when there was relative motion between the solenoid and the wire loop. In other situations such as the one above, however, there is an induced current in the wire loop even though there is no relative motion between the wire loop and the solenoid. There is a general rule called Lenz’ law that we can use in all cases to predict the direction of the induced current

B. Discuss the statement of Lenz’ law in your textbook with your partners. Make sure you understand how it is related to the statement by the student with whom you agreed in part D of section I.
