A Constant Uniform Magnetic Field Of $0.50 \mathrm {~T}$ Is Applied at Right Angles to the Plane of a Applied

Multiple Choice

A constant uniform magnetic field of $0.50 \mathrm {~T}$ is applied at right angles to the plane of a flat rectangular loop of area $3.0 \times 10 ^ { - 3 } \mathrm {~m} ^ { 2 }$ . If the area of this loop changes steadily from its original value to a new value of $1.6 \times 10 ^ { - 3 } \mathrm {~m} ^ { 2 }$ in $1.6 \mathrm {~s}$ , what is the emf induced in the loop?

A) $0 \mathrm {~V}$
B) $7.5 \times 10 ^ { - 2 } \mathrm {~V}$
C) $4.4 \times 10 ^ { - 4 } \mathrm {~V}$
D) $1.6 \times 10 ^ { - 2 } \mathrm {~V}$
E) $9.0 \times 10 ^ { - 2 } \mathrm {~V}$
