Explain the following with suitable examples:
Ferrimagnetism.
Ferrimagnetism.
✓
Answer
Ferrimagnetism:
This effect is observed when the magnetic moments of the domains in the substance are aligned in parallel and anti–parallel directions in unequal numbers. Ferrimagnetic substances are weakly attracted by magnetic field as compared to ferromagnetic substances. Magnetite like $Fe_3O_4$ and ferrites like $MgFe_2O_4$ and $ZnFe_2O_4$ are examples.
