Question

State ampere's circuital law. By using this law find magnetic field iside CC toroidal solenoid.​

Answer 1

Answer:

Ampere's circuital law states: The line integral of the magnetic field, over a closed path, or loop, equals times the total current enclosed by that closed loop. We express this law through the mathematical expression: where , is the net current enclosed by the loop ' 

Explanation:

The magnetic field inside the toroidal solenoid is independent of the radius of the toroid. The magnetic field in the open space inside (point P) and exterior to the toroid (point Q) is zero. According to Ampere's law, if the net current is zero, the magnetic field must be zero.
