As a result of the flow of current through a solenoid, is there any chance of inducing an electric current in the same solenoid ?

The direction of the flow of current through electric circuit is

What is the difference observed in the direction of magnetic field lines on reversing the current through the solenoid ?

Which effect of electricity is made used of in a solenoid ?

Calculate the current flowing through the following circuit:

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.

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.
