You are given a solenoid of length'l', number of turns per unit langth.'n' and area of cross section A.When a current'I' passes through it.What Is the total magnetic flux through the solenoid?

Two solenoids of equal number of turns have theirdengths and radii in the same ratio 1:2 , What is the ratio of their self inductances?

A steady current of 1 amperes is passed through a long solenoid of length l and number of turns N. Obtain a relation for the self inductance of the solenoid.

A steady current of 1 amperes is passed through a long solenoid of length 1 and number of turns N When an alternating! current is applied to an electrical element, the current in it leads the voltage by pi//2 . Identify the- element.
