Multiple-choice questions may continue on the next column or page – find all choices before answering. AP B 1998 MC 48 001 10.0 points A single circular loop of wire in the plane of the page is perpendicular to a uniform magnetic field vector B directed out of the page, as shown. B B If the magnitude of the magnetic field is decreasing, then the induced current in the wire loop is 1. directed upward out of the paper. 2. clockwise around the loop. 3. zero. (No current is induced.) 4. directed downward into the paper. 5. counterclockwise around the loop. cor- rect Flat Coil of Wire 002 10.0 points A flat coil of wire consisting of 38 turns, each with an area of 37 cm 2 , is positioned perpen- dicularly to a uniform magnetic field that in- creases its magnitude at a constant rate from 3 . 6 T to 6 . 6 T in 3 . 1 s. If the coil has a total resistance of 0 . 21 Ω, what is the magnitude of the induced current?the induced current?...
