(a)
The direction of the induced current in the other loop
Answer to Problem 72GP
Solution:
The direction of the induced current in the other loop will be clockwise
Explanation of Solution
Prior to the current in the left-hand circle achieves its enduring state, there will be an incited current in the right-hand circle that will deliver an attractive field into the page to restrict the expansion of the field from the left-hand circle. Subsequently the prompted current will be clockwise.
(b)
The situation after a long time
Answer to Problem 72GP
Solution:
The situation after a long time will be no induced
Explanation of Solution
After quite a while, the current in the left-hand circle is consistent, so there will be no actuated current in the right-hand curl.
(c)
The direction of the induced current in the right hand loop
Answer to Problem 72GP
Solution:
The direction of the induced current in the right hand loop counter clock wise
Explanation of Solution
On the off chance that the second circle is pulled to one side, at that point the attractive field out of the page from the left-hand circle during that time circle will diminish. Amid the movement, there will be an instigated current in the right-hand circle that will deliver an attractive field out of the page to contradict the abatement of the field from the left-hand circle. Therefore the actuated current will be counterclockwise.
(d)
The switch in the left hand loop has been closed a long time when the switch in the right hand loop is closed
Answer to Problem 72GP
Solution:
The switch in the left hand loop has been closed a long time when the switch in the right hand loop is closed will be no effect
Explanation of Solution
Since balance has been achieved ("quite a while"), there is an enduring current in the left-hand circle what's more, relentless attractive motion going through the right-hand circle. There is no emf being initiated in the right-hand circle, so shutting a switch in the right-hand circle has no impact

- Lab-Based Section Use the following information to answer the lab based scenario. A student performed an experiment in an attempt to determine the index of refraction of glass. The student used a laser and a protractor to measure a variety of angles of incidence and refraction through a semi-circular glass prism. The design of the experiment and the student's results are shown below.
