1.	What is the formula of the permeance of the strip in the conductor portion?(a) permeance of the strip = permeability in air * area of the flux path * length of flux path(b) permeance of the strip = permeability in air / area of the flux path * length of flux path(c) permeance of the strip = permeability in air * area of the flux path / length of flux path(d) permeance of the strip =1 / permeability in air * area of the flux path * length of flux pathThis question was addressed to me during an interview.My question comes from Determination of Iron Losses & Slot Leakage in section Principles of Magnetic Circuit Design of Design of Electrical Machines
Answer» RIGHT answer is (c) permeance of the strip = permeability in air * area of the flux PATH / length of flux path For EXPLANATION I would SAY: The permeability in air, area of the flux path and the length of flux path is FIRST calculated. On substitution, the permeance of the strip is obtained.
