Question

(a) If the loop is at rest, what is the induced emf in the loop? in nV

1. What are the magnitude and direction of the induced current in the loop? in pA

direction choices: clockwise, CCW, no current

2. What are the magnitude and direction of the magnetic force on the loop? in N

direction choices: right, left, toward bottom, toward top, out of page, in page, or no force

(b) Repeat if the loop is moving to the left at a constant speed of 55 cm/s.

1. induced emf: in nV

2. induced current: in pA

direction choices: clockwise, CCW, no current

3. magnetic force: in N

direction choices: right, left, toward bottom, toward top, out of page, in page, or no force

Calculate the rate at which an external force, pulling the loop to keep its speed constant, does work.
