Flat Spiral Coil Inductance Calculator

Flat spiral coil is a type of air conductor coil installed in the Tesla generator, RFID tag and proximity detectors. Air core inductor is a type of inductor that is independent of ferromagnetic material to attain any specified inductance. Use our online flat spiral coil inductance calculator to calculate the air core flat spiral inductance. Select the Dimensional units and enter the Outer diameter (d1), Inner diameter (d2) and Number of turns (N) and hit the enter button to get a result.
