Question

Apply ampere's circuital law to find the magnetic field , both inside and out side of a
toroidal solenoid.​

Answer 1

Answer:

Answer yes

→BP = 0.

This is possible only if the magnetic field at point Q vanishes i.e. →BQ= 0.

The number of turns per unit length is n = n2πr2 then the magnetic field at point S is Bs = μ0nI.
