A long narrow solenoid has length l and a total of N turns, each of which has cross-sectional area A. Its inductance is μ₀ ( ).
To find the answer, we need to know about the magnetic field due to a solenoid.
<h3>What is the magnetic field due to a solenoid?</h3>- A solenoid is an insulated wire wound in the form of a helix.
- Its length is very large compared to its diameter.
- The magnetic field due to solenoid carrying current
can be written as,
μ₀n
- We have an expression for magnetic flux as,
Φ Where, A is the area.
- Substituting above value of magnetic field in the expression of magnetic flux, we get,
Ф μ₀
- In terms of inductance, we can express the magnetic flux linked with the coil as,
Ф
- By equating above two equations of magnetic flux, we get the expression for inductance as,
μ₀ ( )
μ₀ (
).
Thus, we can conclude that the expression for inductance is μ₀ ( ).
