Question

A long solenoid with air core has and turn per unit length and carries current I.using ampere's circuital law derive expression for magnetic field B at an interior point on its axis. Write an expression for magnetic intensity H in the interior of the solenoid​

Answer 1

Answer:

The magnetic field inside of a solenoid is made stronger by increasing the number of turns of wire around the core and increasing the current through those coils of wire. Using a core of ferro magnetic material will also effect the strength of the magnetic field.

Answer 2

Answer:

a) Derivation H = nI The direction of H is along the axis of the solenoid, directed along the direction of advance of a right-handed screw rotated along the direction of flow of current
