What's Neodymium Magnet?

Neodymium magnets are a type of rare-earth magnet made from an alloy of neodymium, iron, and boron. They are the strongest type of Permanent Magnet available, with a maximum energy product of up to 52 MGOe (mega gauss-oersteds). Neodymium magnets are used in a variety of applications, including electric motors, wind turbines, hard disk drives, speakers, and medical devices. They are also used in everyday items such as headphones, jewelry clasps, and magnetic therapy products. Neodymium magnets are highly susceptible to corrosion and should be coated or plated to protect them from moisture and oxidation. They are also brittle and can crack or shatter if mishandled.

The difference between Neodymium Magnet and Ferrite Magnet

Neodymium magnets are a type of rare-earth magnet, which are the strongest permanent magnets available. They are made from an alloy of neodymium, iron, and boron and have a very high magnetic energy density. They are commonly used in motors, generators, and speakers.

In summary, neodymium magnets are stronger and more expensive than permanent ferrite magnets, which are more affordable and have good resistance to corrosion. The choice between the two depends on the specific application and magnetic strength required.
