Toroid Inductance Per Turn Calculator

Toroidal inductors are used where large inductance are required at low frequency levels. These are insulated coils in ring shape. As toroid inductors have more number of turns it can carry more currents. This online electrical calculator allows you to calculate the toroid inductance value per turn.

Code to add this calci to your website

Just copy and paste the below code to your webpage where you want to display this calculator.

Formula:

L = 2*N²*μr*h*In(d1/d2) A_e = (h/2) * (d1-d2) L_e = ( π * (d1-d2) ) / In(d1/d2) V_e = A_e * L_e B/I = (0.4π*μr*N) / L_e
Where, L = Inductance N = number of turns μr = Relative permeability h = Core width d1 = Outer diameter d2 = Inner diameter A_e = Effective core area L_e = Effective core length V_e = Effective core volume B/I = Flux Density per Amp

Calculating inductance of a toroid core coil is made easier with this electrical calculator.
