A 18.0cm x 18.0cm square loop of wire lies in the xy-plane with its bottom edge on the x-axis. The resistance of the loop is 0.470 . A magnetic field B parallel to the z-axis is given by 0.810*t*y^2 , where B is in tesla, y in meters, and t in seconds. What is the size of the induced current in the loop at = 0.540 ?
