A square loop of wire with 2.00m sides is perpendicular to a uniform magnetic field that points into the paper. The magnitude of the field varies with time according to B=0.042-0.870 with B in Teslas and t in seconds.
a.) what is the average EMF in the curcuit in the interval of time between t=0 and t-2s?
b.) what is the direction of the current through the resistor? (Fully explain how you get your answer)
