Ferromagnetic and ferrimagnetic substances Magnetic Power

The video tutorial explains different types of magnetic substances: ferromagnetic, antiferromagnetic, and ferrimagnetic. Ferromagnetic substances, like iron, cobalt, and nickel, exhibit permanent magnetism. Antiferromagnetic substances have equal parallel and anti-parallel magnetic moments, resulting in no net magnetism. Examples include manganese dioxide and ferric oxide. Ferrimagnetic substances have unequal magnetic moments, leading to a net magnetic moment, as seen in magnetite and ferrite. Heating can convert ferromagnetic and ferrimagnetic substances into paramagnetic substances.

Describe the characteristics of ferrimagnetic substances.

What happens to ferromagnetic and ferrimagnetic substances when subjected to heating?
