Wire Pair Inductance

Wire Pair Inductance Inductance Calculators

Wire Pair Inductance Model
Inductance of the loop bounded by the wire pair is:
wire_pair_formulas
Units: Henries

Description
The inductance calculated using this tool is the external inductance the loop bounded by the wire pair over the wire length, circular wire. Internal inductance, which is negligibly small in many circumstances, is not included in this model, but may be calculated using the Wire Internal Inductance tool.

Assumptions and Limitations
Dimensions are in meters.
Wires are assumed to have circular cross sections and to be uniformly spaced over their length Wires are assumed to reside in a homogeneous medium having permeability u=u0.

Constants
Permeability of free space: Formula, Permeability of Free Space H/m
