Which method needed to limit cross-magnetizing effect?(a) by increasin

1.	Which method needed to limit cross-magnetizing effect?(a) by increasing reluctance of cross flux path(b) by chamfering the pole faces(c) by compensating winding(d) any of the mentionedThe question was posed to me in a job interview.My doubt stems from MMF and Flux Density Waveforms in DC Machines in chapter DC Machines of Electrical Machines
Answer» The correct choice is (a) by INCREASING reluctance of CROSS flux path Explanation: By ultimately increasing the reluctance of the magnetic circuit at the pole tips so that the armature REACTION EFFECT is neutralized.
