Circuit1: Symmetric double line of conductors

Problem Type:
A plane-parallel problem of AC magnetic field analysis.

Geometry:
Two copper conductors with square cross-sections carrying opposingly directed currents of equal magnitudes are contained inside the rectangular ferromagnetic coating. All dimensions are in millimeters.

Given:
The same as in the HMagn2 example. The current source is specified by the circuit.

Problem:
The current distribution within the conductors and the coating, complex impedance of the line, and power losses in the coating should be determined.

Results:
