Rare earth magnets - Interesting facts

Interesting facts about rare earth magnets

We often see how rare earth magnets are being used for a variety of purposes. The excellent strength and performance offered by these magnets contribute a lot towards the above-mentioned fact. You will be able to create strong magnetic fields with the assistance of rare earth magnets. These magnets can be found in a variety of applications. For example, you can find them inside electronics and kid’s toys. On top of that, you will also be able to find rare earth magnets being used along with the fishing magnets.

While keeping these facts in mind, let’s take a look at some of the interesting facts about rare earth magnets.

They are stronger than regular magnets

One of the most obvious facts about rare earth magnets is that they are stronger than rare earth magnets. In fact, these magnets are around three times stronger when compared to ordinary magnets that you can find.

The magnetic properties of a magnet are being measured through a parameter called tesla. The magnetic power that you can find in an ordinary magnet is around 0.5 tesla. But when you take a look at a rare earth magnet, you will figure out that the magnetic power is around 1.5 tesla. When you have a requirement to use strong magnets, you should think about going forward with rare earth magnets. These magnets would never disappoint you.

They were initially introduced during the 1960s

Rare earth magnets were introduced to the world during the recent past. In fact, the very first instance where rare earth magnets were discovered during the 1960s. Due to the same reason, you can think about calling them as a relatively modern invention out there.

These magnets were discovered at the United States Air Force Materials Laboratory. Soon after rare earth magnets were discovered, people got to know about the benefits offered by them. As a result, manufacturers started using them for a variety of products. As of now, you will be able to get rare earth magnets along with numerous business products as well as consumer products that exist out there in the market.

These magnets are heat resistant

When you take a look at rare earth magnets, you can find numerous unique properties in them. One of the most interesting properties that you can find out of them is that they are highly resistant to heat. When you compare rare earth magnets with the standard magnets, you can clearly understand the excellent heat resistant properties offered by them. Due to the same reason, you will even be able to use them in applications, where you need to provide protection against heat.

You will also notice that some of the variations of rare earth magnets are more heat resistant when compared to the others. For example, the rare earth magnet called Samarium Cobalt has the ability to offer a high level of heat resistance when compared to others. They are in a position to withstand a heat resistance of up to 500 degrees Fahrenheit as well. When you are exposing the rare earth magnet to such high temperatures, the magnetic properties will never be lost.

Rare earth magnets are vulnerable to corrosion

Even though the rare earth magnets are highly strong, they are still vulnerable to corrosion. This can be considered as the biggest drawback associated with the magnets. Due to the same reason, people are kept away from using rare earth magnets for some of the applications as well.

The rare earth magnets are subjected to corrosion when they are exposed to oxygen and moisture. Therefore, it is important for you to take protection against rare earth magnets at all times. However, you will still be able to add some additives and enhance the overall resistance shown by rare earth magnets against corrosion.

For example, we can see how the neodymium rare earth magnets are being coasted with nickel, zinc, and gold. This would create a protective layer on top of the rare earth magnets. As a result, it is possible to discourage corrosion that can take place.

They last long

If you are trying to purchase long-lasting magnets, you will need to take a look at the rare earth magnets. It is completely natural for the magnets to lose the magnetic properties along with time. However, the rare earth magnets lose their magnetic properties slowly along with time.

According to the studies, an average magnet would lose its magnetic properties by around 5% in every 100 years. However, rare earth magnets are losing only a small percentage of it. Due to the same reason, you will find it as an easy task to use rare earth magnets for a longer period of time.

They are inexpensive

Some of the people believe that rare earth magnets are expensive. But when you take a look at the big picture, you will notice that rare earth magnets are relatively inexpensive. These magnets were associated with a very high price tag until the 1990s. However, the manufacturing techniques associated with rare earth magnets were changed in the recent past. As a result, you will now be able to purchase rare earth magnets at an affordable price tag. This is the same reason on why you will be able to use them as fishing magnets as well.

Final words

Now you have a clear picture on what is offered along with rare earth magnets. Keep these factors in mind and start using the rare earth magnets for different purposes you have. These magnets can help you to complete activities that you cannot complete with the traditional magnets out there. Along with this understanding, you can think about purchasing rare earth magnets for your needs as well. Hence, you will never come across any confusions when you are purchasing products that come along with rare earth magnets.
