1. Four loops of wire move near a long straight wire carrying a current as shown in the figure. Find the direction of the induced current in each of the four loops. A C D B A. B. C. D. 2. A flexible loop of wire has an initial radius of 12.0 cm and sits in a magnetic field of 0.15 T as shown. The wire is grasped at points A and B and stretched until the area is approximately zero. If it takes 0.20 s to stretch the loop, what is (a) the magnitude of the average induced emf and, (b) which way will the induced current run in the loop? 3. As the bar magnet moves to the right, what is the direction of the current in the resistor? S N
