A toroidal solenoid has 500 turns, cross-sectional area 6.30 cm2 , and mean radius 5.00 cm .

PART A

Calcualte the coil's self-inductance.

PART B

If the current decreases uniformly from 5.00 A to 2.00 A in 3.00 ms, calculate the self-induced emf in the coil.

PART C

The current is directed from terminal a of the coil to terminal b. Is the direction of the induced emf from ato b or from b to a?
