1. A method for generating an electromagnetic field (EMF) model for an electric device, the method comprising: establishing a time-domain finite data model associated with the electric device, wherein the time-domain finite data model defines a basic system representation of the electric device in the time-domain; utilizing the time domain finite data model to determine a plurality of excitations representing an electrical characteristic of one or more electrical components of the electric device; and generating an EMF model by processing the plurality of excitations with a transformation routine determining an approximate representation of an EMF generated by the electric device.
