A square wire loop with L= 1 m sides is perpendicular to a uniform magnetic field, with half the area of the loop in the field (see Fig.). the resistance of the loop is 35 ohm and the loop contains an ideal battery with emf = 6 V . if magnitude of the field varies with time according to B = 5 – 2t , with B is testlals and t in seconds what are (a) the net emf in the circuit (b) the direction of the current around the loop.
