The Magnetic neutral axis or plane (M.N.A)coincides with the
geometrical neutral axis or plane (G.N.A).M.N.A may be
defined as the axis along which no e.m.f is produced in the
armature conductors or the axis which is perpendicular to the
flux passing through armature.

Answer / dhanunjayareddy

the axis along which the resultant induced emf is zero across the conductor which is rotating
