Question

X1. A circular loop of flexible iron wire has an initial circumference of 165.0 cm, but its circumference is decreasing at a constant rate of 12 cm/s due to a tangential pull on the wire. The loop is in a constant, uniform magnetic field oriented perpendicular to the plane of the loop and with magnitude 0.50 T. (a) Find the emf induced in the loop at the instant when 9.0 s have passed. (b) Find the direction of the induced current in the loop as viewed looking along the direction of the magnetic field.

Step 1

First, we need to find the circumference of the loop after 9.0 seconds. Since the circumference is decreasing at a rate of 12 cm/s, after 9.0 seconds, the decrease in circumference will be 12 cm/s * 9.0 s = 108 cm. Show more…
