magnetic field around two copper bars, time-harmonic magnetic field analysis

This example is prepared by Didier Werke AG, InduCer Group, Abraham Lincoln Str. 1,65 189 Wiesbaden, Germany

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 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.
