ElectroMagnetic InductionHard
Question
The number of turns, cross-sectional area and length for four solenoids are given in the following table.
The solenoid with maximum self inductance is :
The solenoid with maximum self inductance is :
Options
A.1
B.2
C.3
D.4
Solution
(D) L = μ0n2πr2l
A = πr2
n =
⇒ L = 
By putting the given values, it can be seen that it is maximum for solenoid no.4.
A = πr2
n =
⇒ L = By putting the given values, it can be seen that it is maximum for solenoid no.4.
