Neodymium magnet is the most popular type of magnet. It is made of iron, boron and neodymium. It has tetragonal crystalline structure. Nd2Fe14B is the chemical composition of Neodymium Magnets. In 1982, it was founded by Sumimoto Special metals.

It is one of the strongest magnets in the world nowadays. It is also one of the most permanent type of magnet in the world. Previous strongest magnet named Alnico was easily replaced by Neo Magnets with its strong molecular composition. Since 1982, It has become very important part of today's world. This very durable magnets are used in many manufacturing goods. Although since it is rare, the use of Neo Magnets are costly.

They are also used widely in the electronic technology. For example, your computer hard drive has head actuator that is made of Neo Magnet. It is also crucial component of different types of manufacturing products such as cars, engines and motors.

Surprisingly, jewelry is one of the industries where neodymium is used. Jewelry that sell for millions of dollars every day, has magnetic properties in them. Also, magnetic jewelry is known for their healing uses since the old times. This types of jewelry are used for treatment of bone related problems. Doctors even suggest to use magnetic jewelry for depression and mental disorder treatment.

History

In 1982, Sumimoto Special metals was first who discovered neodymium magnets. The company started the development of it because they needed to replace previous strongest magnet because of its high cost. Sumimoto Special Metals worked with General Motors on creation of Neodymium.

The new magnet captured the market very fast. Ferrite magnet was quickly replaced by neodymium magnets in all the manufacturing factories.

Other uses of Neodymium Magnet

- Astronauts in NASA use it for the muscle tone maintenance.

- Toy industries use it to make toys for kids.

- It is essential part of MRI scanning machines.

- Generators use it and it essential part of how good the generator is. Stronger magnet makes better generator in general.

- Students who take advanced physics, often use it for scientific researches.

- Security systems have it in them.

- Adults and the kids often use it as a toy as it is very entertaining.

- Lots of metal detectors have it in them.

Because of the smaller size and lower cost than other permanent magnets, Neodymium Magnets are used in variety of manufacturing fields.
