Suppose a conducting loop consisting of a half circle of radius of 0.20 m and 3 straight sections. The half circle lies in a uniform magnetic field that is directed out of the page; the field magnitude is given by B = 4.0t2 + 2.0t + 3.0, with B in teslas and t in seconds. An ideal battery with emf 2.0 V is connected to the loop. The resistance of the loop is 2.0 ohms. What are the magnitude and direction of the emf induced around the loop by field B at 10s? What is the current in the loop at 10s
