A circular wire loop with a radius of 0.49 m

is located in an external magnetic field of

strength +0.17 T that is perpendicular to the

plane of the loop. The field strength changes

to −0.24 T in 2.2 s. (The plus and minus signs for a magnetic field refer to opposite

directions through the coil.)

Find the magnitude of the average induced

emf during this interval.

Answer in units of V.
