Question

The self inductance of a long solenoid carrying current is independent of (A) its length (B) The current (C) Its cross-sectional area (D) Magnetic permeability of the core

Tardigrade Admin · Accepted Answer

Self-Inductance of a solenoid is given by

L = \frac{μ _{0} N ^{2} A}{l}

where,

N =

number of turns in solenoid

l =

length of the solenoid

A =

area of one turn of solenoid.
The self-inductance of solenoid does not depend on current passing through it.

Q. The self inductance of a long solenoid carrying current is independent of

its length

The current

Its cross-sectional area

Magnetic permeability of the core

The number of turns

Self-Inductance of a solenoid is given by $L = \frac{μ _{0} N ^{2} A}{l}$
where, $N =$ number of turns in solenoid
$l =$ length of the solenoid
$A =$ area of one turn of solenoid.
The self-inductance of solenoid does not depend on current passing through it.
