Question

In permanant magnet at room temperature?

Answer 1

Explanation:

At room temperature, the permanent magnet retains ferromagnetic property for a long period of time. The individual atoms in a ferromagnetic material possess a dipole moment as in a paramagnetic material. ... Thus, we can say that in a permanent magnet at room temperature, domains are all perfectly aligned.

Mark me as a brainlist thankyou.

Answer 2

Answer:

Even in the case of a permanent magnet all the domains are not perfectly aligned due to thermal agitations.
