A toroidal solenoid has 800 turns, cross-sectional area of 16.25 cm^2, and an average radius of 14.00 cm. a) Calculate the self-inductance of the coil. b) If the current decreases uniformly from 15.00 A to 12.00 A In 3.00 ms, calculate the self-induced electromotive force in the coil. c) Current is directed from terminal a of the coil to terminal b. Is the direction of the induced electromotive force from a to b, or from b to a? Why?
