One of the most popular rare-earth magnets is known as neodymium magnets.  If you are familiar with this rare-earth material, then you probably know that it has an extremely high magnetic field and it has a few common uses. For example, it is often used for resonance imaging. It is used in the production of head actuators for the HDDs used in the computer your using at the moment. Neodymium magnets are also used for manufacturing spindle motors and synchronous.

Neodymium Magnet – The Strongest Magnet on the Planet

Have you ever wondered why neodymium magnets are often referred to as the ‘rare-earth’? It is rare-earth because it contains composition elements that originate from the lanthanides portion of the Periodic Table of Elements.

When some people think about neodymium magnets, they assume it has been around since the beginning of time. In reality, it was only discovered in the early 1980s by GM, China Academy of Science and Sumitomo Special Metals.  This came at a good time because there was a high demand for an affordable replacement.  Before the discovery, SmCo permanent magnets were considered the hot item of moment that was becoming more and more expensive to use.

What is Neodymium magnets Made of?

Neodymium magnets are a composite of boron and iron. It is also referred to as NIB, NdFeB and Neo. Another interesting fact about neodymium magnets is that it has powerful magnetic properties and it has superior resistance to demagnetization. Most magnets are not as strong and it’s magnet properties remain well-preserved for several years. If you take a collection of magnetic products, it will deliver the most powerful magnetic energies of any material available.

In the 21^st century, neodymium magnets are used in several applications in technology such as the following:

·         alarms

·         guitar pickups

·         jewelry clasps

·         children’s toy sets

·         computer hard disks

·         electrical power steering

·         headphones

·         loudspeakers, etc.

In addition, neodymium magnets are often used in MRI machines within the health industry.

Neodymium magnets are basically produced in two forms – bonded magnet process and sintered (powdered).  According to statistics, around 5500 tons of bonded magnets and around 50,000 tons of sintered magnets are produced annually. 

As you’ve probably noticed from the list above, neodymium magnets are used in mechanics and it is also portable. Best of all, it is inexpensive. You can find this magnet in neodymium ring magnets and neodymium disc magnets. There is only one drawback, it is can be corrosive.

In high temperatures it can actually catch on fire. It works best in lower temperatures.  It is important to note that neodymium magnets can snap your finger if you’re not cautious. Neodymium magnets should be handled with care.
