Solution: A constant magnetic field of 0.70 T is applied to a rectangular loop of area 3.4×10 -3 m2. If the area of this loop changes from its original value to a new value of 1.6×10 -3 m2 in 1.6 s, what is the emf induced in the loop?
A) 0 V
B) 7.9 x 10 -4 V
C) 1.6 x 10 -2 V
D) 7.5 x 10 -2 V

A constant magnetic field of 0.70 T is applied to a rectangular loop of area 3.4×10 ^{-3} m^{2}. If the area of this loop changes from its original value to a new value of 1.6×10 ^{-3} m^{2} in 1.6 s, what is the *emf* induced in the loop?

A) 0 V

B) 7.9 x 10 ^{-4} V

C) 1.6 x 10 ^{-2} V

D) 7.5 x 10 ^{-2} V
