The effect of fringing increases as we _________(a) increase air gap(b

1.	The effect of fringing increases as we _________(a) increase air gap(b) decrease air gap(c) increase in flux density(d) introduce more ferric core materialI have been asked this question in an internship interview.My question is taken from DC Motor Starting topic in section DC Motors of Electrical Machines
Answer» The CORRECT option is (a) increase air gap For EXPLANATION: Fringing is the EFFECT in which the magnetic flux lines BULGE out of the flux. and it is introduced at the air GAPS.
