The magnetic field shown in the figure below has a uniform magnitude of29.0mT directed into the paper. The initial diameter of the kink is 2.00 cm.A uniform magnetic field points into the page. A long, thin wire goes horizontally to the right, then curves around clockwise to form a single circular loop of diameter 2.00 cm below the straight part of the wire. As the wire completes its loop, it continues to the right, with the wire coming out from the loop underneath the wire at the beginning of the loop. The leftmost point of the wire is labeledAand the rightmost point of the wire is labeledB.(a) The wire is quickly pulled taut, and the kink shrinks to a diameter of zero in49.0ms. Determine the average voltage induced between endpointsAandB. Include the polarity.

magnitude	mV
polarity	---Select--- A is positive relative to B. B is positive relative to A. The voltage is zero.

(b) Suppose the kink is undisturbed, but the magnetic field increases to101mT in4.05?10^?3s. Determine the average voltage across terminalsAandB, including polarity, during this period.
