Have You Thought about the Advantages of Rare Earth Block Magnets?

Posted on

How much do you know about the power of magnetism? At school most people will have learned about the way poles of a magnet can either attract or repel each other. They may also learn about how electromagnets work and the principles behind their operations, but how many people understand the real-world application of magnetism and how many products we use each day rely on magnets to function? You might be surprised to know that magnetism is an essential principle for everything from hand power tools to maglev trains. If you are designing a new product you should consider whether using magnetism could be the right engineering approach for you.

Are all magnets the same?

While the principles of magnetism are universal not all magnets equally strong. For many applications, an alnico or a conventional ferrite magnet will be ideal but that isn't always the case. Sometimes you will need a higher level of performance and on those occasions, you will need to investigate the use of rare earth block magnets. Rare earth block magnets are especially strong permanent magnets and are frequently used in industry and transport applications.

How are rare earth block magnets made?

The majority of rare earth block magnets that you will find used in industry today are neodymium magnets. These magnets are created using an alloy of neodymium combined with boron and iron. You could also find that small amounts of dysprosium and praseodymium have been include in some grades of rare earth block magnets. The different grades of rare earth block magnets relate to the relative magnetic strength of the magnet but they also have operational implications. Standard grades of these magnets are operated at lower temperatures than magnets made from samarium cobalt. When these magnets are uncoated they can also be subject to corrosion so it is advisable to find a way of protecting them. If you employ a higher grade of rare earth magnet then you will discover that there are less operational restrictions.

Could you use rare earth block magnets?

One of the advantages of rare earth block magnets is that they possess greater strength than traditional magnets; this means that you can have the same level of magnetism as a traditional magnet in a smaller, lighter package. The ability to reduce the size and weight of magnets in many devices has led to the widespread adoption of rare earth block magnets in many applications. To find out if they are suitable for your needs, why not talk to your nearest supplier today?
