I need help on both parts
Assume that the length of the solenoid is much larger than the solenoid's radius and that the core of the solenoid is air. Calculate the inductance of a uniformly wound solenoid having 210 turns if the length of the solenoid is 26 cm and its cross-sectional area is 5 cm^2. Calculate the self-induced emf in the solenoid described in the first part if the current through it is decreasing at the rate of 62...
