Ideal magnetomotive force source
The MMF Source block represents an ideal magnetomotive force (mmf) source that is powerful enough to maintain specified constant mmf across its output terminals, regardless of the flux flowing through the source.
You specify the output mmf by using the Constant mmf parameter, which can be positive, negative, or zero.
Output mmf. You can specify any real value. The default value
The block has two magnetic conserving ports associated with its terminals.
