Model Data

Type: electromagnetics

Physics Modes: magnetostatics

Keywords: verification

This example calculates the inductance between parallel wires. Two 1 m wires with 4 mm radius 1 A current are placed 0.5 m apart in a large domain of non-conducting air or vacuum. The inductance is computed with both using the magnetic field energy and flux linkage, and compared against the analytical solution L = (µ0/π⋅l⋅(ln(d/r)+¼)).
