Faraday's Law: the Three Loops of Wire Shown in the Figure

Multiple Choice

Faraday's law: The three loops of wire shown in the figure are all subject to the same uniform magnetic field that does not vary with time.

Which loop, or loops, will have an emf induced in them?

A) loop 1 only
B) loop 2 only
C) loop 3 only
D) loops 1 and 2
E) loops 2 and 3
