The figure below shows a flexible loop of metal wire with a radius of 13.0 cm. It lies in a magnetic field pointing into the page with a magnitude of 0.160 T. A student grabs the loop at points A and B and rapidly pulls in opposite directions until the loop folds up, such that its area becomes zero. The change in area occurs in a span of 0.250 S.
