In a permanent magnet at room temperature.
  1. Magnetic moment of each molecule is zero
  2. The individual molecules have non-zero magnetic moment which are all perfectly aligned
  3. Domains are partially aligned
  4. Domains are all perfectly aligned

A
Domains are all perfectly aligned
B
The individual molecules have non-zero magnetic moment which are all perfectly aligned
C
Domains are partially aligned
D
Magnetic moment of each molecule is zero
Solution
Verified by Toppr

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