# Toroid Inductance Calculator

Toroid Inductance is an insulated circular coil wounded around a doughnut shaped magnetic core. It is a passive electronic component, created using the ferromagnetic material such as laminated iron, iron powder, or ferrite. It is capable of carrying more electric current as it carries more inductance at each turn. Toroid inductance calculator to find the toroid inductance based on the number of turns, height, inner radius, outer radius and permeability of free Space.

#### Formula:

Inductance = ( N ^{2} × H × μ_{0} × ln ( B / A ) ) / ( 2 × π )
**Where,**
N = Number of Turns
H = Height
μ_{0} = Permeability of Free Space (4 × π × 10^{-7})
B = Outer Radius
A = Inner Radius
Toroid Inductance which is widely applicable in the electronic circuits like supplies, inverters, and amplifiers can be found using toroid inductance calculator. It is compact and light weight than any other cores.
