A flexible circular coil of radius 10 cm consisting of 5 turns of wire is placed in a magnetic field directed perpendicular to the plane of the loop as shown in the figure below. P B X X X X a. If the magnetic field is incresed from 0.15 T to 0.42 T in a time of 0.13 s, determine the magnitude of the induced emf (aka induced voltage) in the coil and the direction of the current induced ε = V Direction of the induced current: Select an answer b. Now, the magnetic field is held fixed at 0.42 T as the flexible coil is grasped at points P and Q and stretched (toward the top and bottom of the page) until its area goes to zero in a time of 0.19 s as the loop is closed. Determine the magnitude of the induced emf (aka induced voltage) in the coil and the direction
