The correct option is C.

Answer 2

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

The correct option is C.

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.
The correct option is C.

The saturation magnetization $M_{m a x}$ of the ferromagnetic metal nickel is $4.70 \times 1 0^{5} A / m$ . Calculate the magnetic dipole moment of a single nickel atom. (The density of nickel is $8.90 g / c m^{3}$ and its molar mass is $58.71 g / m o l$ .)

A domain in ferromagnetic iron in the form of cube is having $5 \times 1 0^{10}$ atoms. If the side length of this domain is $1.5 μ m$ and each atom has a dipole moment of $8 \times 1 0^{- 24}$ A $m^{2}$ , then magnetisation of domain is?
