The image below contains an inductor of inductance L (Henries) and a time-varying current from a power supply flowing from A to B. (a) At what rate would the current through the inductor have to change to induce a negative emf of V (volts) in the inductor? Use the variables given in the problem to write your answer. Include the correct sign. (b) what direction would that induced current flow (A to B or B to A) and why? Write your answers to (a) and (b) in the text box and include a one-sentence explanation of your part (b) answer to receive full credit.
