The working flux travels through both the core and the air
gap.The ampere turn required to overcome the reluctance in
air gap is very large as compared to the iron or core
parts.In rotating machines, about 60-70 % of the total
ampere turns per pole are required for the air gap.So the
air gap length should be AS SMALL AS MECHANICALLY POSSIBLE.
