A loop with resistance 2.0 \OmegaΩ is oriented as shown below inside a region of uniform and constant external magnetic field. The B-field lines point straight upwards. The dashed parts of the loop are behind the screen and the solid parts of the loop are in front of the screen. The normal to the loop is parallel to the external B-field lines initially. The external magnetic field has a magnitude of 0.5 T and the area of the loop is 0.25 m2. The loop is then rotated by 25° around the axis shown in 1.5 s. The magnitude of the average induced current that flows around the loop while it is rotating is: 0 A 0.0078 A 0.0833 A 0.0378 A 0.0039 A
