Definitions for "Magnetic Circuit"
Keywords:  ferromagnetic, gap, flux, pole, path
The path in which magnetic flux flows from one magnet pole to the other.
The circuit that includes the magnet(s), the top plate, and the pole piece; they combine to create a magnetic field in the air gap where the voice coil sits.
Consists of all elements, including air gaps and non-magnetic materials that the magnetic flux from a magnet travels on, starting from the north pole of the magnet to the south pole.
