A long straight wire lying along the x-axis carries a constant 5 A current along the positive x direction. A small 5mm diameter loop lies in the x-y plane centered at y = 2m. If the loop is suddenly stretched so that its area shrinks to zero in 0.2s, find the average induced emf in the coil assuming the B field is constant over its area. Draw a sketch showing the direction of the induced current
