An air-cored solenoid has 150 turns and cross-sectional area `2 cm^(2)`. If it is 40 cm long, what is its self-inductance?

An air core solenoid has 1000 turns and is one metre long. Its cross-sectional area is 10cm^(2) . Its self-inductance is

A circular coil with a cross-sectional area of 4cm^(2) has 10 "turns" / cm . It is placed at the centre of a long solenoid that has 15 "turns" / cm and a cross-sectional area of 10 cm^(2). The axis of the coil coincides with the axis of the solenoid. What is their mutual inductance ?
