Eddy Current Excitations

Eddy Current T-W Excitations

For the Eddy Current T-W solver, the following sources of AC magnetic fields are available:

Excitation	Type of Excitation
Current Density	The current density in a conductor. In this case, you must also define the current density terminals for the conductor.
Current Density Terminal	Specifies the cross-section of the conductor where current density is specified, to be used as a terminal object. Current Density and Current Density Terminal are required to be used in conjunction.
Current	The total current in a conductor.
Coil Terminal	Used to define one or more model windings.
Winding With Current	Current for both a stranded and solid conductor.
Winding With Voltage	Voltage for both a stranded and solid conductor.
Winding With External Circuit Connection	External circuit connection for both a stranded and solid conductor.

Note: When entering current, the arrow associated with current in the selected object shows the direction as if a positive value is entered for the current. If a negative value is entered the actual current flow direction is opposite to what the arrow shows. Click Reverse Direction if you want to reverse the direction of the arrow.

Note: When a source conductor touches an outer boundary, Maxwell assumes current will flow perpendicular to the boundary. If you do not want current to cross the outer boundary, an insulating boundary should be used.
