A toroid has a core (non-ferromagnetic) ...

A toroid has a core (non-ferromagnetic) of inner radius 25 cm and outer radius 26 cm, around which 3500 turns of a wire are wound. If the current in the wire is 11 A, what is the magnetic field outside the toroid,

Text Solution

Verified by Experts

For outside the toroid, the magnetic field is zero, because the magnetic field due to toroid is only inside it and along the length of toroid.
