A solenoid is made by wrapping a wire so that it makes a solenoid (coil) having 500 turns of diameter 8.00 cm and length 40.0 cm.
(a) Find the inductance of this solenoid.
(b) If the current in this solenoid increases at the rate of 3.00 ampere per second, find the self-induced emf in the solenoid.
(c) If the current is steady at 3.0 A, what is the self induced emf.
