A five turn square loop (10 cm on an edge and resistance = 4.0 ohms) is placed in a magnetic field that makes an angle of 30 degrees with the plane of the loop. The magnitude of this field varies with the time according to B = 0.50 t^2, where t is measured in seconds and B in Tesla, T. What is the induced current in the coil at t = 4.0 s?
