With automated referencing and data interpolation for higher accuracy results The formula for calculating the self-capacitance of an air-core single-layer solenoid is: Inductance of multilayer coils. Most practical air-core inductors are multilayer cylindrical coils with square cross-sections to minimize average distance between turns (circular cross -sections would be better but harder to form). Magnetic cores. Many inductors include a magnetic core at the center of or partly surrounding the winding. 1 mH = 0.001 H. 1 μH = 0.000001 = 10⁻⁶ H. 1 nH = 0.000000001 = 10⁻⁹ H. 1 pH = 0.000000000001 = 10⁻¹² H. See our Inductance Calculator.. Inductance characterizes the ability of an electrical conductor to convert changes in electric current into changes in electrical potential in both this conductor (self-inductance) and in any nearby conductors (mutual inductance). Jul 17, 2020 · Coil32 is inductance coil calculator, that allows to calculate the single-layer and multi-layer air core inductors, the ferrite toroid inductors or chokes, flat square coils on PCB etc. This calculator uses Maxwell’s formula for the mutual inductance between two circular filaments, applied to every combination of wire pairs in the coil, and then summed to determine the total inductance.
