Field distribution around two copper bars

At Didiers Quickfield has been used to calculate AC-electromagnetic and heat transfer problems in the course of the development of the "InduCer"- technology. The sample given here is dedicated to pure electromagnetic problem: field distribution around two copper bars.

Problem Type:
A plane problem of time-harmonic magnetic field.

Geometry:

two copper bars model

Two copper bars with equal but opposite currents.

Given:
Magnetic permeability of air μ = 1;
Magnetic permeability of copper μ = 1;
Conductivity of copper σ = 56 000 000 S/m;
Current in the conductors I = 1880 A;
Frequency f = 10 000 Hz.
