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.
