Question

In picture, a flat conducting loop of wire of dimensions h = 50.0 cm by l = 30.0 cm is immersed perpendicularly in a magnetic field which changes with time, B(t) = t4 - 3t3 - 6t2 + 4t + 2. The diagram shows t = 0, where B > 0 indicates that the magnetic field is coming out of the paper. The resistanceless wire is connected to a resistor R = 30.0 ft Find when the induced cmf is a max. Determine the magnitude and direction of the current in the loop. when the induced cmf is a min. Determine the magnitude and direction of the current in the loop.
