A coil composed of five circular loops of wire (area of each loop is 0.125 m^2) lies in the plane of this sheet of paper. A magnetic field pointed perpendicular out of the sheet of paper (towards us), and begins at a strength of 2.5 tesla. Over 0.025 seconds, the magnetic field reduces to zero tesla. (a) Calculate the induced voltage in this coil caused by this changing magnetic field.

(b) What direction will current flow around this coil (clockwise or counterclockwise)? Use Lenz' law.
