Question

what are toroid?? what is magnetic field associated with it??​

Answer 1

Answer:

A toroid is a coil of insulated or enameled wire wound on a donut-shaped form made of powdered iron. A toroid is used as an inductor in electronic circuits, especially at low frequencies where comparatively large inductances are necessary. ... In a toroid, all the magnetic flux is contained in the core material

Magnetic Field of Toroid

Magnetic Field of ToroidThe toroid is a useful device used in everything from tape heads to tokamaks. For a solenoid of radius r = m with N = turns, the turn density is n=N/(2πr)= turns/m. ... The Earth's magnetic field is about half a gauss.
