Question: A long straight wire carrying a current I is in the plane of a circular loop of wire. See the figure with Multiple- Choice Question

A long straight wire carrying a current I is in the plane of a circular loop of wire. See the figure with Multiple- Choice Question 4. The current I is decreasing. Both the loop and the wire are held in place by external forces. The loop has resistance 24 Ω.
(a) In what direction does the induced current in the loop flow?
(b) In what direction is the external force holding the loop in place?
(c) At one instant, the induced current in the loop is 84 mA. What is the rate of change of the magnetic flux through the loop at that instant in webers per second?
