Question

Is ${\mathrm{MgFe}}_2{\mathrm{O}}_4$ ferromagnetic?

Answer 1

Explanation:

1. Ferromagnetic Substances- A substance which shows ferromagnetism is called a ferromagnetic substance.
2. Ferromagnetism is the property of materials being attracted to magnets.
3. Ferromagnetism is also a permanent property of a material.
4. A ferromagnetic material is weaker in its attraction towards an applied magnetic field than paramagnetic substances.
5. Ferromagnetism is temperature-dependent.
6. ${\mathrm{MgFe}}_2{\mathrm{O}}_4$ is a ferromagnetic substance when it is heated to a particular temperature, it becomes paramagnetic.

Hence, ${\mathrm{MgFe}}_2{\mathrm{O}}_4$ is a ferromagnetic substance at room temperature.
