What type of substances would make better permanent magnets, ferromagnetic or ferrimagnetic. Justify your answer.

Explanation

Ferromagnetic substances make better permanent magnets than ferrimagnetic substances. The metal ions of a ferromagnetic substance are grouped into small regions known as domains. When magnetic field is applied, all the domains get oriented in the direction of magnetic field and a strong magnetic field is removed, ferromagnetic substance behave as a magnet. This impart permanent magnetic character to these substances However this property is lacking in ferrimagnetic substances Therefore ferromaynetic substances are better magnets
