Transient Excitations

After defining the coil terminals for the model, you can use these terminals to define one or more windings using the Maxwell > Excitations > Add Winding option. Transient problems use the following sources of magnetic fields:

Excitation	Type of Excitation
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: A winding is a flexible excitation. Six different combinations can be used: Current, Voltage, and External Circuit — each with a solid or stranded conductor. The Coil Terminal type of excitation is needed to set up a winding.

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.

In addition, permanent magnets serve as sources of magnetic fields.
