What are rare earth magnets and their applications? TyTek Industries explains…

Rare Earth Magnets are strong permanent magnets that aren’t actually ‘rare’

Although their title may suggest that they are hard to find, rare earth magnets are actually plentiful around the world and the ‘rare’ term pertains to a classification of certain minerals. They are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets. The two most used rare earth alloys are Neodymium (NdFeB) and Samarium cobalt (SmCo).

Main characteristics of Neodymium (NdFeB): 

• It’s the most affordable of the two magnets
• High coercivity (high resistance to being demagnetized)
• High saturation magnetization; giving the ability for storing large amounts of magnetic energy.

Main characteristics of Samarium cobalt (SmCo):

• Strong properties but more brittle compare to Neodymium which means they need to be handled correctly
• Higher Curie temperature; (providing high field strength even at high operating temperatures)
• Highly resistant to oxidation, corrosion and demagnetisation.

What are the main applications for rare earth magnets?

To the general person, we are unaware of where rare earth magnets are utilized and their significance. But as the market trends in technology and consumer products change, so do the applications of rare earth magnets. The most common applications include: medical devices and technology such as MRI scanners, headphones and speakers, jet engines, roller coasters and many more. More recently, with the net zero agenda being pushed worldwide this has brought a significant increase in demand for wind turbine technology and electric vehicles. Rare earth magnets are heavily utilized here, in starter generators and motors for example, which means that the rare earth magnet market is on the rise.
