What is permeance ?
Ans :-
It is the reciprocal of reluctance & is a measure of the ease with
which magnetic flux can pass through the material . Its unit is
Wb/AT .
Permeance = 1/Reluctance
It is the property of a material which encourages magnetic flux
to pass through the material . Permeance of a magnetic circuit
corresponds to conductance in an electric circuit .
