the closed path described by magnetic flux. It is analogous to the electric circuit with resistance, where flux, reluctance, and magnetomotive force correspond to electric current, resistance, and electromotive force.
Provide thermal magnetic circuit breaker or fused switch with external operator and incoming line fuses.
In the drawing, the iron of the magnetic circuit and the copper tube are shaded.
All circuit breakers shall be molded-case thermal-magnetic circuit breakers.
Each pair of pole pieces has a solenoid coil attached with a top bar to complete the magnetic circuit.
Encyclopedia Article for magnetic circuit
closed path to which a magnetic field, represented as lines of magnetic flux, is confined. In contrast to an electric circuit through which electric charge flows, nothing actually flows in a magnetic circuit.
