Discussion
The analogous of conductance in magnetic circuit is __________.
Answer: C
The magnetic analogue of conductance is permeance.
A magnetic circuit is treated like an electric one: mmf corresponds to emf, flux to current, and reluctance to resistance, giving flux = mmf / reluctance. Conductance is the reciprocal of resistance, so its counterpart is the reciprocal of reluctance, which is permeance.
Reluctance is the analogue of resistance, not conductance. Flux is the analogue of current, and permeability is the material property that corresponds to conductivity, not to the conductance of a whole circuit.
