The coefficient of self inductance of a solenoid is 0.18 mH. If a cor...
The coefficient of self-inductance of a solenoid can be calculated using the formula:

L = (μ₀ * μᵣ * N² * A) / l

Where:
L is the coefficient of self-inductance
μ₀ is the permeability of free space (4π * 10⁻⁷ Tm/A)
μᵣ is the relative permeability of the core material
N is the number of turns in the solenoid
A is the cross-sectional area of the solenoid
l is the length of the solenoid

In this case, the coefficient of self-inductance is given as 0.18 mH (millihenries), and the relative permeability of the soft iron core is given as 900.

To find the new coefficient of self-inductance with the soft iron core, we need to calculate the new value of L using the given values.

Let's assume the original coefficient of self-inductance without the core is L₀, and the new coefficient of self-inductance with the core is L.

So, we can write the equation as:

L = L₀ * μᵣ

To find L, we need to find L₀ first.

Let's assume the original coefficient of self-inductance without the core as L₀.

Now, we can rearrange the formula for L to solve for L₀:

L₀ = L / μᵣ

Substituting the given values:

L₀ = 0.18 mH / 900

L₀ = 0.0002 mH

So, the original coefficient of self-inductance without the core is 0.0002 mH.

Now, we can find the new coefficient of self-inductance with the soft iron core:

L = L₀ * μᵣ

Substituting the values:

L = 0.0002 mH * 900

L = 0.18 mH

Therefore, the coefficient of self-inductance will become nearly 162 mH when a core of soft iron with a relative permeability of 900 is inserted. Hence, the correct answer is option B.
