For a simple gapped inductor, with a magnetic circuit with a uniform cross-sectional area throughout the whole magnetic path, the value of inductance L can be calculated from the following equation:

Note: The equation is valid only for a simple magnetic circuit, with cross-sectional area of the core and gap being equal, and if lcore » lgap, and µcore » 1.
