expression of produced magnetic field at the
centre of a long current carrying solenoid with
its help.

Answer 1

Answer:

Ampere's circuital law can be written as the line integral of the magnetic field surrounding closed-loop equals to the number of times the algebraic sum of currents passing through the loop.

the required expression for the magnetic field in the solenoid is μ0nIa2r3.

Answer 2

Explanation;-

Ampere's circuital law is the relationship between the current and magnetic field .
According to ampere's circuital law the line integral of magnetic field , around a close path is equal to the product of magnetic permeability of that space and the total current through the area bounded by that path.
