A ferromagnetic substance becomes a permanent magnet when it is placed in a magnetic field because:

A

all the domains get oriented in the direction of magnetic field

B

all the domains get oriented in the direction opposite to the direaction o magnetic field

C

Domains get ori ented randomy

D

Domains are not affected by magnetic field

Text Solution

Verified by Experts

The correct Answer is:
A
when a ferromagnetic substance is placed in a magnetic field it becacomes a permanent mangnet magnet because all the dominas get oriented in the directions of magnetic field even after removal of applied magnetic field.
