A solenoid of length `l` metre has self-inductance `L` henry. If number of turns are doubled, its self-inductance

If the length and area of cross-section of an inductor remain same but the number of turns is doubled, its self-inductance will become-

The number of turns of a coil is doubled. How will its self-inductance be effected?

The self-inductance of a long straight solenoid is L. Each of the length, the diameter and the number of turns of another solenoid is double that of the first. The self-inductance of the second solenoid is

The self inductance L of a solenoid of length l and area of cross section A, with a fixed number of turns N increases as

A wire of fixed length is wound on a solenoid of length l and radius r . Its self-inductance is found to be L . Now, if the same wire is wound on a solenoid of length l//2 and radius r//2 then the self-inductance will be

A wire of fixed length is wound on a solenoid of length l and redius r . Its self-inductance is found to be L . Now, if the same wire is wound on a solenoid of length l//2 and redius r//2 then the self-inductance will be
