Symmetric double line of conductors

QuickField simulation example

This is an example of the symmetric double line of conductors simulation, performed with QuickField software.

Problem Type
Plane-parallel problem of AC magnetics.

Geometry
Symmetric double line of conductors Two copper conductors with square cross-sections carrying opposing directed currents of equal magnitudes are contained inside the rectangular ferromagnetic coating. Coating Conductor 1 Conductor 2 Air 40 mm 20 mm Symmetric double line of conductors electric circuit This is an example of the symmetric double line of conductors simulation, performed with QuickField software.

Two copper conductors with square cross-sections carrying opposing directed currents of equal magnitudes are contained inside the rectangular ferromagnetic coating.

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

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

Results
Current density distribution in the conductors
