question 74

Multiple Choice

A constant uniform magnetic field of 0.50 T is applied at right angles to the plane of a flat rectangular loop of area 3.0 × $10 ^ { - 3 }$ $m ^ { 2 }$ . If the area of this loop changes steadily 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)1.6 × \(10 ^ { - 2 }\) V
• B)0 V
• C)7.5 × \(10 ^ { - 2 }\) V
• D)4.4 × \(10 ^ { - 4 }\) V
• E)9.0 × \(10 ^ { - 2 }\) V
