Question:

Suppose you are looking at two wire loops in the plane of the page as shown in Fig. 21-64. When switch S is closed in the left-hand coil,
(a) What is the direction of the induced current in the other loop?
(b) What is the situation after a "long" time?
(c) What is the direction of the induced current in the right-hand loop if that loop is quickly pulled horizontally to the right?
(d) Suppose the right-hand loop also has a switch like the left-hand loop. The switch in the left-hand loop has been closed a long time when the switch in the right-hand loop is closed. What happens in this case? Explain each answer.
