Rare earth magnets are known to be the strongest magnets in the world. That makes them valuable even though they are small. Their strength makes them applicable in various fields. You are sure to come close to a neodymium magnet almost every day in this modern life. If you are planning to use a rare earth magnet, you should find the right one. Each type of neodymium magnet contains unique features. The type of magnet you choose depends on how you plan to use it. Here are the aspects to consider before getting a rare earth neodymium magnet.
Analyse the Heat Resistance
The magnetic field is never constant. A change in temperature affects the strength of the rare magnet. You should, therefore, look at the temperature in the specific application. Some rare earth magnets will do best under high temperatures. But other magnets are best suited for lower temperatures. For example, ferrite rare earth magnets will perform well in temperatures between -40 degrees Celsius and 150 degrees Celsius. On the other hand, neodymium earth magnets will lose their magnetism when the temperatures get to 100 degrees Celsius. Thus, you should examine the operating temperatures where you wish to install your magnet. That way, you end up with the right type of rare earth magnet.
Consider Their Magnetic Output
The strength of the magnet determines how you can use it. The force of the magnet is quantified by two factors. These are the residual induction and the maximum energy product. Residual induction refers to the energy required to remove a magnet on a block. The maximum energy product is used when calculating the motor performance of the rare earth magnet. The lifting capacity of the magnet is weak if it has a low magnetic output.
How Available Is It?
From the name, it is evident that rare earth magnets are not easy to find. These magnets also need a lot of labour during extraction. Additionally, the production process should be controlled for you to maintain its purity. Thus, knowing how easy it is to find the magnet you need for the application is vital. Some of the rare earth magnets, such as neodymium, are easy to find. But, sourcing other kinds of rare earth magnets can prove to be a problem.
Rare earth magnets are suitable for various applications. For you to enjoy the benefits that come with using rare earth magnets, work to find the right one. Working with a professional in the field will ensure you get the right magnet to use.Share
