Made up of rare earth and alloys elements, a rare earth magnet is a strong permanent magnet, which includes samarium, neodymium, praseodymium, and 13 other elements. These elements in the 1800s were reportedly discovered but it wasn’t until when in the late ’60s it was developed in a U.S. Air Force lab where cobalt and samarium were produced the largest magnetic anisotropy.
This means that a magnetized object from Magnet Factory in China could resist being pulled in another direction as the magnetic force was very great.
Samarium-cobalt magnets and neodymium magnets are the two most popular rare earth magnets. Neodymium is considered to be the strongest and affordable kind. It’s used for hard drives, electric motors and jewellery clasps, for cordless tools. Meanwhile, samarium-cobalt is commonly used by industrial manufacturers and is considered to be on the pricey side.
To replace the permanent magnet they use, a few car manufacturers and Clean tech developers are reportedly seeking. According to a Reuters report, Both Toyota and GM are trying to reduce their dependence and usage of rare earths.
To make electric cars, Toyota has in fact found a way without rare earths and not needing permanent magnets, Renault SA has made electric motors. However, still the best magnet to use is the permanent magnet as GM reps say.
Self-powered flashlights, stop motion animation, roller coaster technology, neodymium magnet toys, electric guitar pick-ups, and diamagnetic levitation experimentation are included in some interesting applications for the Rare Earth Magnet.
It is quite hazardous, as well as essential and advantageous it is to certain industries. With great care, it needs to be handled because they break into pieces and splinter at high speed when these magnets come together.
Also, when they come into contact against the skin, they squeeze powerfully. But they are needed in the world. And it helps pull things along efficiently; whatever you’re riding the roller coaster or doing-rocking an electric guitar wherever you are.
