Answer Posted / dilip kumar
Magnetostriction is the effect due to non uniform arrangement domain or grain in the core material.
when alternating current is passed through the core having non uniform grain arrangement, then for every positive and negative cycle the transformer core tries to expand and contract (100 times/sec for 50Hz transformer), due to which some fast vibrations are produced on the transformer,which inturn produces a humming noise in the transformer), it cannot be avoided.
Magnetostriction can be minimized by using the cores which have more uniform grain orientation. (eg:CRGO)
TO totally avoid the Magnetostriction effect, one should go for DC instead of AC (where you can't say that as a transformer anymore).
HOPE IT HELPS!!!
