Q:

Liquids and gases never show

A) diamagnetic property B) paramagnetic property
C) ferromagnetic property D) electromagnetic property
 
Answer & Explanation Answer: C) ferromagnetic property

Explanation:

On the basis of magnetic properties, substances are classified into three groups namely diamagnetic, paramagnetic and ferromagnetic.

As solids diffuse and reorder very slowly under ambient conditions, the net, directionally dependent (anisotropic) magnetic moment can persist. Conversely, liquids and gases freely tumble and reorder: water rearranges every few pico seconds (10^12 times per second).

Hence liquids and gases can never show ferromagnetic properties.
