WebFeb 23, 2024 · The outside and inside the magnetic field of a toroid is zero. The direction of the magnetic field inside a toroid always happens to be clockwise. A toroid mostly looks like a solenoid that can be bent into a circular shape in order to close it into a loop structure. The magnetic field due to a toroid can be expressed as, WebExample 2: Toroid A toroid consists of N turns and has a rectangular cross section, with inner radius a, outer radius b and height h (see figure). (a) Find its self-inductance L. (b) Find the total magnetic energy stored in the toroid. Solution: (a) To find the self-inductance, we first need to know the magnetic field everywhere.

WebJun 7, 2015 · Surface area of a torus. One can generate a torus as follows: g → = ( ( b + a cos u) cos v, ( b + a cos u) sin v, a sin u). To find its area, we can use a surface integral of the form S = ∬ D u v ‖ ∂ g ∂ u × ∂ g ∂ v ‖ d u d v. However, in the case of torus the integral becomes seemingly unnecessarily tedious to evaluate.
