Hi can you plese help me with the assignment A square conducting loop with a side of 9m and a total resistance of 3.5 Ω is perpendicular to a homogeneous magnetic field that extends over half of the area of loop. The magnitude of the magnetic induction varies with time according to the relationship B=0.042-4*t, where B is in [T]Tesla and time t is in [s]seconds. Determine the induced current in the loop if we consider that positive values represent a counter-clockwise current. Thank you
