Question: A square wire loop with 2.2 m sides is perpendicular to a uniform magnetic field, with half the area of the loop in the field

A square wire loop with 2.2 m sides is perpendicular to a uniform magnetic field, with half the area of the loop in the field as shown in the figure. The loop contains an ideal battery with emf 8 = 18 V. If the magnitude of the field varies with time according to B = 0.040 - 0.89 t, with B in teslas and t in seconds, what are (a) the net emf in the circuit and (b) the direction of the (net) current around the loop? & bat (a) V (b) counterclockwise
