Step by Step Process to Calculate Inductance of Solenoid

Below provided are the steps for calculating the self-inductance of a solenoid easily.

  • Check the number of turns, radius, length of the solenoid.
  • Find the area of cross-section from the radius of the solenoid.

  • Divide the product by the solenoid length to get the inductance of a solenoid.

Inductance of a Solenoid

A solenoid is a coil that is used in RLC Circuit. The characteristic inductance act as an interial element. The change in current flows through a coil is the self-induced potential difference.

The voltage in the solenoid is the ratio between the potential and the rate of change of current.

V = -L x dI/dt

The inductance of a solenoid can be stated as

L = µ₀ * N² * A/l

Where,

L is the self-inductance of a solenoid

N is the number of turns

r is the coil radius

A is the area of cross-section of the solenoid

l is the length

µ₀ is the vacuum permeability and its value is 1.25664 * 10-6 T*m/A

Example

Question: A solenoid has 33 turns and carries a current of 4 amps. It has a radius of 5 cm, length of 8 cm find its inductance?

Solution:

Given that

Number of turns of solenoid N = 33

Radius r = 5 cm

Length l = 8 cm = 0.08 m

Coss section area A = πr²

A = π x 5 x 5

= 78.54 cm² = 0.007854 m²

Inductance of the solenoid L = µ₀ * N² * A/l

L = 1.25664 x 10-6 x 33² * 0.007854/0.08

= 134.35 µH

Therefore, the inductance of a solenoid is 134.35 µH.
