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.

i wanna say it’s between b and d, leaning more towards b.

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary
