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.

an assembly consisting of some or all of the following: permanent magnets, ferromagnetic conduction elements, air gaps, and electrical currents.

An assembly consisting of some or all of the following: permanent magnets, ferromagnetic conduction elements, air gap s, electrical currents.

The complete path of a magnet's lines of force.

A magnetic circuit is a closed path containing a magnetic flux. It generally contains magnetic elements such as permanent magnets, ferromagnetic materials and electromagnets, but may also contain air gaps and other materials.
