![]() At the top are the equations for calculating number of turns, based on the AL value, and AL based on the number of turns. A small ferrite core transformer makes the broad band impedance. ![]() The calculators below can be used to determine the proper parameters for either a circular or square cross section Toroid inductor. Credit for the initial Javascript code used in the calculator is given to Ray Allen who has a number of similar useful calculators on his website, Pulsed Power Portal. Ferrite Toroidal Cores On the right is a simple calculator for determining the number of turns required for a particular core materal. An antenna tuner is an electronic device insered into the feedline between a radio. ![]() Where N is the number of turns, h is the height of the winding (in cm), r 1 is the inner radius (in cm), and r 2 is the outer radius (in cm). The inductance of a rectangle loop has three geometric variables: W rectangle long side h rectangle short side d wire diameter Rectangle Loop Inductance Model. Alternate Equation for a Square Cross Section Toroid Inductor The rectangle loop is often found in windings for transformers or ferrite cores.
