4. [14-pts) In the figure below, the radius of the loop is 20cm; the magnitude of the magnetic field through the loop increases according to the relation B :7.0t2+6.0t, where B is in Tesla and t is in seconds. (a) What is the magnitude of the emf induced in the loop when t:2.0 s? (b) Is the direction of the current through R to the right or left
