PHYSICS 12th Ampere circuital law to calculate unit 3
AMPERE’S CIRCUITAL LAW:
Ampere’s circuital law states that line integral of magnetic field forming a closed loop around the current(i) carrying wire, in the plane normal to the current, is equal to the μo times the net current passing through the close loop. -

The solenoid 12th physics,
A solenoid is a coil with the length greater than its diameter and is a type of an electromagnet to produce controlled magnetic fields by passing an electric current through it.
Derivation of Bar Magnet as an Equivalent Solenoid
By calculating the axial field of a finite solenoid carrying current, bar magnet can be demonstrated as a solenoid. Consider a solenoid of radius a and length 2l with n number of turns per unit length that has current I passing through the solenoid. Considering a small element of thickness dx of the solenoid at distance x from O such that OP = r. -
