Question

KollegeApply · Accepted Answer

In a permanent magnet at room temperature domains are all perfectly aligned. Explanation: At room temperature permanent magnet behaves as a ferromagnetic substance for a long period of time. 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. However, they interact with one another in such a way that they spontaneously align themselves in a common direction over a macroscopic volume called domain. Thus, we can say that in a permanent magnet at room temperature, domains are all perfectly aligned.
