Samarium cobalt (SmCo) magnets are a type of rare earth magnet that was invented in the early 1970s by General Motors and Sumitomo Special Metals. The invention of SmCo magnets revolutionized the world of magnetism and has since become one of the most widely used magnets in the world.
The invention of SmCo magnets was a result of the need for a stronger and more reliable magnet than the traditional ferrite and alnico magnets. Ferrite and alnico magnets had been used for decades, but their strength was limited and they were prone to corrosion. General Motors and Sumitomo Special Metals recognized the need for a stronger and more reliable magnet and began researching and developing a new type of magnet.
The research and development process was long and arduous, but eventually the two companies were able to create a new type of magnet that was stronger and more reliable than any other magnet on the market. This new type of magnet was made from a combination of samarium and cobalt, and was given the name “Samarium Cobalt” or “SmCo”.
The invention of SmCo magnets was a major breakthrough in the world of magnetism. SmCo magnets are much stronger than traditional ferrite and alnico magnets, and they are also much more resistant to corrosion. This makes them ideal for use in a variety of applications, such as motors, generators, and sensors.
SmCo magnets are also much more expensive than traditional ferrite and alnico magnets, but their superior strength and reliability make them well worth the cost. In addition, SmCo magnets are much smaller than traditional magnets, making them ideal for use in small, compact devices.
The invention of SmCo magnets has had a major impact on the world of magnetism. SmCo magnets are now used in a variety of applications, from motors and generators to sensors and medical devices. They are also used in a variety of consumer products, such as headphones, speakers, and computer hard drives.
