Question 5 • Physics

Which actions most likely cause the domains within a material to lose their alignment and become more randomized? Choose three correct answers.

Answer
A
placing the material near a strong magnet
B
hitting the material
C
placing the material in a magnetic field of opposite polarity
D
passing electricity around the material
E
heating the material
F
rubbing the material against a magnet

Explanation

Magnetic domains can become less aligned when the material is disturbed by impacts or heated, which increases the motion of its particles. A magnetic field of opposite polarity can also disrupt or reverse the existing alignment. A strong magnet, electric current, or rubbing with a magnet is more likely to align the domains rather than randomize them.
