Question
The figure below shows a flexible loop of metal wire with a radius of 12.0 cm. It lies in a magnetic field pointing into the page with a magnitude of 0.140 T. A physicist 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 0.210 s. x A x x x x x * x x x x x x .x x x B x x What is the average induced emf (in mV) in the loop over this time span? mV
