Question

Is${\mathrm{Fe}}_3{\mathrm{O}}_4$ ferromagnetic?

Answer 1

${\mathrm{Fe}}_3{\mathrm{O}}_4$ is ferromagnetic at room temperature because The magnetic numbers of $\mathrm{Fe}\left(\mathrm{II}\right)$ and $\mathrm{Fe}\left(\mathrm{III}\right)$ ions in Its crystals are unequal in magnitude and parallel in orientation.

Ferromagnetic: Long-range ordering is a physical phenomenon is called ferromagnetism, which is the strong attraction between certain materials such as iron. It is Rare earth elements, including gadolinium, are present in ferromagnets.

1. Magnetism in objects like magnets is due to a frequent occurrence in everyday life.
2. Ions and atoms in ferromagnetic materials must have constant magnetic moments.
3. Some ions and atoms include a permanent magnetic moment, similar to a dipole, with a north pole and a south pole.

Hence, it ${\mathrm{Fe}}_3{\mathrm{O}}_4$is ferromagnetic.
