A loop of wire sits in a uniform magnetic field, everywhere pointing toward you. Due to a changing magnetic flux through the loop, an induced current flows in the wire, clockwise as shown. The area of the loop is 0.660 m^2, and the magnetic field initially has magnitude 0.540 T. Suppose that, over a time period of 1.91 s, the magnetic field changes from its initial value, producing an average induced voltage of 0.149 V. What is the final value of the magnetic field after this time period? 0.680 T 1.262 T 0.971 T 0.194 T
