1.	Explain the following properties giving suitable examples. (i) Ferromagnetism (ii) Para magnetism (iii) Ferrimagnetism
Answer» Ferromagnetism:- Ferromagnetic substances are those substances which shows permanent magnetism when magnetic field is removed. For example:- Fe, CrO₂ (ii) Para magnetism:- Paramagnetic substances are those which are attracted by an external magnetic field but they lose their magnetism in the absence of a magnetic field due to the presence of atoms, molecules or ions containing unpaired electrons. For example:- Cu²⁺,Fe³⁺,O₂,Cr³⁺ etc. (iii) Ferrimagnetism:- Ferrimagnetism substances are those substances in which the magnetic moments are aligned in parallel and anti-parallel directions in unequal numbers resulting in net magnetic moment. For example:-Fe₃O₄,Ferrites MgFe₂O₄

Explain the following properties giving suitable examples. (i) Ferromagnetism (ii) Para magnetism (iii) Ferrimagnetism

Answer»

Ferromagnetism:- Ferromagnetic substances are those substances which shows permanent magnetism when magnetic field is removed.

For example:- Fe, CrO₂

(ii) Para magnetism:- Paramagnetic substances are those which are attracted by an external magnetic field but they lose their magnetism in the absence of a magnetic field due to the presence of atoms, molecules or ions containing unpaired electrons.

For example:- Cu²⁺,Fe³⁺,O₂,Cr³⁺ etc.

(iii) Ferrimagnetism:- Ferrimagnetism substances are those substances in which the magnetic moments are aligned in parallel and anti-parallel directions in unequal numbers resulting in net magnetic moment.

For example:-Fe₃O₄,Ferrites MgFe₂O₄
