Question

Most materials are not magnetic because

Answer 1

C. their magnetic domains are arranged randomly

In magnetized materials, all or most of the magnetic domains are arranged in the same direction 

Answer 2

Answer:

c. their magnetic domains are arranged randomly.      

Explanation:

A material is classified as a magnetic material if its domains are oriented in a single direction or can be oriented in the presence of a magnetic field. Example: iron, nickel, cobalt and materials made of their combination.

In non-magnetic materials, domains are randomly arranged. For example wood, silicon etc.

Due to heat or hammering, a magnet can lose magnetic properties as the orientation of domains becomes random.
