question 38

Multiple Choice

A rectangular loop (area = 0.15 m2) turns in a uniform magnetic field with B = 0.20 T.At an instant when the angle between the magnetic field and the normal to the plane of the loop is ( $\pi$ /2) rad and increasing at the rate of 0.60 rad/s, what is the magnitude of the emf induced in the loop?

• A)24 mV
• B)zero
• C)18 mV
• D)20 mV
• E)6.0 mV
