Question

In a permanent magnet at room temperature (A) Magnetic moment of each molecule is zero (B) The individual molecules have non-zero magnetic moment which are all perfectly aligned (C) Domains are partially aligned (D) Domains are all perfectly aligned

Tardigrade Admin · Accepted Answer

A permanent magnet at room temperature retains a ferromagnetic property that possesses a dipole moment. And domains are partially aligned due to thermal agitation.

Q. In a permanent magnet at room temperature

Magnetic moment of each molecule is zero

The individual molecules have non-zero magnetic moment which are all perfectly aligned

Domains are partially aligned

Domains are all perfectly aligned

A permanent magnet at room temperature retains a ferromagnetic property that possesses a dipole moment. And domains are partially aligned due to thermal agitation.
