When conductors are placed in an electric field, their electrons are moved
Opposite to applied field
In a direction of applied field
Randomly in all direction
May be randomly or in direction of applied field
Electrons in a conductor moves in opposite direction when placed in an electric field.
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 a magnetic field
(b) all the domains get oriented in the direction opposite to the direction of a magnetic field
(c) domains get oriented randomly
(d) domains are not affected by a magnetic field
