Rare earth magnets are the strongest permanent magnets found on earth. Due to their strength, rare earth magnets such as Neodymium have replaced ferrite and alnico magnets which were in use before the discovery of rare earth magnets. Rare earth magnets are extremely strong magnets that can crush an object placed in between two magnets […]
A magnet’s strength is based on its structure and how it is magnetized. Strong magnets include ferrite, alnico, neodymium, and samarium-cobalt magnets. Ferrite and Alnico magnets are made from naturally magnetized minerals. Both of these magnets were the strongest magnets until the invention of rare earth magnets, neodymium and samarium magnets.
