Question

4. A long straight wire carrying a current is in the plane of a circular loop of wire. The current is decreasing. Both the loop and the wire are held in place by external forces. The loop has a resistance of 24. -Long wire Conducting loop a) In what direction does the induced current in the loop flow? Mint: first find the external magnetic field at the loop due to the long wire, figure out if the flux through the loop is increasing or decreasing and apply Lenz's low. 0 CW ii) CCW i) There is no induced current in the loop. b) In what direction is the external force holding the loop in place? toward the straight wire away from the straight wire ini) to the right iv) to the left v] out of the page vi) into the page vii) there is no magnetic force on the loop from the wire. c) At one instant, the induced current in the loop is 94 mA. What is the rate of change of the magnetic flux through the loop at that instant? (hint: use Faraday's law of induction)
