Our free inductance calculators calculate inductance of 11 different conductor configurations. 60 has worked out a variety of cases for polygons with side length s and wire. No closed-form exists to calculate the inductance of a generic polygon of wire.

The values for μ r and σ are from Transmission Line Design Handbook by Brian C Wadell, Artech House 1991 Table 9.3. EMI Software provides dozens of online calculators, free. For this reason, the inductance of complicated shapes can often be well approximated by a simpler shape with the same perimeter and/or area. The absolute magnetic permeability (μ) = μ o x μ r Self inductance is not typically measured, since it is only part of a complete circuit loop. Μ is the absolute magnetic permeability of the conductor The inductance of a single conductor is called self inductance. Two more formulas are given by Brian Wadell for calculating T(x) which are "accurate to a few percent over the range 0.0 ≤ x ≤ 100.0". The partial inductance of the conductor segment can be defined as the ratio between the magnetic flux generated by the conductors current between this segment. The formula originates from Inductance Calculations by F W Grover, Van Nostrand, Princeton, NJ, 1947, Reprinted by Dover Publications, NY, 1962. The self inductance of a straight wire at high frequency is: The calculation of inductance of wire loops is of practical importance in power electronics, motor design and other applications. The capacitance per unit length of the cable has already been calculated. For more information seeįrom Transmission Line Design Handbook by Brian C Wadell, Artech House 1991 page 382 paragraph 6.2.1.1 Self-Inductance of a Coaxial Cable shows two long, concentric cylindrical shells of radii and As discussed in Capacitance on capacitance, this configuration is a simplified representation of a coaxial cable.
