The figure shows a conducting loop consisting of a half-circle of radius r and three straight sections. The half-circle lies in a uniform magnetic field B that is directed out of the page and is increasing with time. The radius and the magnetic field are given by the following: r = 0.20 m, B(t) = 3.0t^2 + 4.0t + 2.0. The area of the circle is given by Tr^2. What direction is the induced current in the loop? Suppose the resistance of the loop is R = 2.0 Ω. What is the magnitude of the induced current at time 15 s?
