Homework Answers
initially outer loop have current in counter clock wise direction and both loop have magnetic flux in direction out of the page. when switch is opened and current decrease flux coming out of both loop decrease so induced current will be in a direction so that induced flux will be out of page in both loop so in both loop induced current is counterclockwise.

In this problem, you will use Lenz's law to explore what happens when an electromagnet is activated a short distance from a wire loop. You will need to use the right-hand rule to find the direction of the induced current. When the switch is open, which of the following statements about the magnetic flux through the wire loop is true? Assume that the direction of the vector area of the wire loop is to the right. There is no magnetic...

The drawing depicts a copper loop lying flat on a table (not shown) and connected to a battery via a closed switch. The current I in the loop generates the magnetic field lines shown in the drawing. The switch is then opened and the current goes to zero. There are also two smaller conducting loops A and B lying flat on the table, but not connected to batteries. Determine the direction of the induced current in (a) loop A and...

Not sure if there isn't enough information since the left loop
is increasing while the right loop is decreasing flux. Or is it
clockwise? I would love an explanation.
