magnetostriction- the magnetic materials have a structure
called domains., as for AC, the domain in the materials
rotate for every magnetisation and demagnetisation cycles..,
by selecting proper core grades we can reduce the M.effect,
the core which has low hystersis has less M.effect
the magnetostriction also due to improper GRAIN ORIENTED
MOMENTS in the material,
So CRGO silicon sheets are used, wher there is a proper
grain orientation
CRGO-cold rolled grain oriented.
