When did neodymium magnets come out?

### Development of Neodymium Magnets.

Neodymium magnets are a type of permanent magnet made from an alloy of neodymium, iron, and boron. The development of these magnets was a significant breakthrough in the field of magnetic materials. Prior to neodymium magnets, the most commonly used magnets were ceramic (ferrite) magnets and Alnico magnets, which were much weaker in terms of magnetic properties.

The development of neodymium magnets was a collaborative effort between General Motors and Sumitomo Special Metals. The two companies worked together to create a new type of magnet that would be stronger and more efficient than any other magnet on the market. After years of research and development, the first neodymium magnets were produced in 1984.

### Properties of Neodymium Magnets.

Neodymium magnets are known for their incredible strength and magnetic properties. They are the strongest type of permanent magnet available today, with magnetic field strengths that can be over ten times greater than traditional magnets. Neodymium magnets also have high coercivity, meaning they are resistant to demagnetization and can retain their magnetism for a long time.

One of the key properties of neodymium magnets is their high energy density, which allows them to generate a strong magnetic field in a relatively small size. This makes them ideal for applications where space is limited, such as in electric motors, speakers, and magnetic clasps. Neodymium magnets are also highly resistant to demagnetization, making them a durable and long-lasting magnet option.

### Applications of Neodymium Magnets.

Neodymium magnets are used in a wide range of applications due to their strength and magnetic properties. They are commonly found in consumer electronics, such as smartphones, headphones, and hard drives. Neodymium magnets are also used in medical devices, such as MRI machines and pacemakers, where a strong magnetic field is required.

In addition, neodymium magnets are used in industrial applications, such as in magnetic separation, lifting equipment, and magnetic couplings. Their strength and efficiency make them a popular choice for various industries that require powerful magnets for their operations. Overall, the versatility and capabilities of neodymium magnets have made them an essential component in many modern technologies.
