The three loops of wire shown in the figure are all subject to the same uniform magnetic field B that does not vary with time. Loop 1 oscillates (through small angles, so that the loops stays in the field) back and forth as the bob in a pendulum, loop 2 rotates about a vertical axis, and loop 3 oscillates up and down (over small distances, so that the loops stays in the field) at the end of a spring. Which loop, or loops, will have an emf induced in them? B A) loops 1 and 2 B) loops 2 and 3 C) loops 3 and 1 D) loop 1 only E) loop 2 only F) loop 3 only O O O
