Question

Find magnetic field at a point inside a current carrying solenoid by using ampere circuit law

Answer 1

A solenoid bent into the form of a closed ring is called a toroidal solenoid. Alternatively, it is an anchor ring around which a large number of turns of a metallic wire are wound. We shall see that the magnetic field B→ has a constant magnitude everywhere inside the toroid while it is zero in the open space interior (point P) and exterior (point Q) to the toroid.

The direction of the magnetic field inside is clockwise as per the right-hand thumb rule for circular loops. Three circular Amperean loops as shown by dashed lines. By symmetry, the magnetic field should be tangential to them and constant in magnitude for each of the loops.hope it helps you.please mark as brilliant
