Gapped Core Inductance Calculation

In gapped core, a smaller portion of the flux path is replaced by non-magnetic medium and filled with air, nylon or any material instead of ferromagnetic material. The function of the air gap here is to control the inductance and increase the quality factor. The online calculator is designed to calculate gapped core inductance by selecting the units and entering the values of core length, gap area, gap length, relative permeability and number of turns.
