What is the main difference between a permanent magnet and a temporary magnet

a. a permanent magnet is made if a ferromagnetic material, while a temporay magnetic is hot

b. a temporay magnet attracts only metal objects, while permanent magnets attract both metal and other objects
c. the domains is a temporayu magnet easily lose alignment but the domains in a permanent magnet keep their aligment
d. there are domains in a permant magnet not in pemporary magnet

Option (C) is the correct answer.

Explanation:

In a temporary magnet, the atoms are not aligned unless and until they encounter a strong magnetic field. Therefore, domains of a temporary magnet easily lose alignment.

Whereas the atoms in a permanent magnet remain aligned even in the absence of external magnetic field. But when we provide heat to a permanent magnet then its atoms start to rearrange themselves and convert into temporary magnet.

Hence, we can conclude that out of the given options, the main difference between a permanent magnet and a temporary magnet is that the domains is a temporary magnet easily lose alignment but the domains in a permanent magnet keep their alignment.

it is the second option.
