Toroid is

A wire carrying current of 5 A is wound on a toroid in 4,000 turns, Calculate the magnetic field inside the core of toroid and outside the toroid if its inner radius is 15 cm and the outer radius is 18 cm.

Determine the mutual inductance of a toroid and an infinite straight wire located along the central axis of the toroid. The toroid has a rectangular cross section with inner and outer radii a and b respectively. The width of the rectangular cross section parallel to the straight wire is h. Total turns in the toroid is N.

What is Toroid? Calculate the magnetic field at a point Open space exterior to the toroid

(a) How is a toroid different from a solenoid? (b) Show that in an ideal toroid, the magnetic field (i) inside the toroid and (ii) outside the toroid at any point in the open space is zero.

Current I is following through a toroidal solenoid of radius r, length l and area A. If the number of turns of toroidal solenoid is N, then energy stored in the toroidal solenoid is …..
