Problem Description
ourse
A circular loop with a radius of 9.0 cm with a resistance of 0.4512 is placed within a uniform 0.35-T B field
pointing into the page so that the surface of the loop is perpendicular to the field. You collapse the coil into a
long, thin shape in 0.2 seconds. Determine the average magnitude and direction of the current induced in this
loop during this process. State any assumptions you make.

Instructions
In a neat and organized fashion, write out a solution to the problem above which includes all of the following:
• A fully-labeled sketch of the physical situation which includes all relevant objects and moments in time.
• A flux-time graph which represents how the flux through the loop changes during this process and
whatever representations are needed to determine the direction of the induced current.
• Use the information provided and your representations to determine the average magnitude and direction
of the current induced in the loop while it is being collapsed. Explain each step in your solution as you
make it. If you use any Right-Hand Rules, explain how you used them (just saying "I used the right-hand
rule to determine the direction of the current" is not sufficient).
• An evaluation of your solution (not just your final answer).
