Advanced Magnet Source Explores the Fascinating World of Permanent Magnets

In the article on magnets from BYJU’s Physics, the concept of permanent magnets is thoroughly explained. These magnets are widely used and retain their magnetic properties once magnetized. However, there are ways to demagnetize them, such as subjecting them to extreme temperatures, hammering, or stroking them with other magnets.

The article highlights four types of permanent magnets: ceramic or ferrite magnets, Alnico magnets, Samarium Cobalt (SmCo) magnets, and Neodymium Iron Boron (NIB) magnets. Each type possesses unique characteristics and applications.

In contrast, temporary magnets can be magnetized in the presence of a magnetic field but lose their magnetism once the field is removed. Everyday objects like iron nails and paper clips can exhibit temporary magnetic properties.
