the three loops of wire shown in the figure are all subject to the same uniform magnetic field that does not vary with time. loop 1 oscillates back and forth as the bob in a pendulum, loop 2 rotates about a vertical axis, and loop 3 oscillates up and down at the end of a spring. which loop, or loops, will have an emf induced in them?

Loop 2 will have an induced EMF.

We can arrive at this answer because:

  • EMF is induced in loops that can be rotated, as the magnetic flux only changes the magnetic field through one rotation.
  • In the figure below, we can see that Loop 1 is not being rotated, but swung from left to right.
  • Loop 3 is also not being rotated, but pushed up and down.
  • Loop 2 is being rotated, so it is in this loop that we can see an induced EMF.

The figure below was taken from questions like yours and the movement of each loop can be seen by the arrows.
