Most people will be familiar with the power of magnetism. Not everyone, however, is aware is the wide application of magnetism or how magnetized products and devices that make our lives easier and more convenient. Today, you will find magnetism being used in power tools, medical equipment and a wide variety of industrial applications.
The changing face of magnetism
While magnetism has been extensively used for many decades in both the industrial and commercial worlds, that doesn't mean that there have been no changes or advances in the field of magnetism over the years. In technology in general, the trend has always been for devices to become physically smaller in size while, at the same time becoming more powerful. Traditionally, permanent ferrite or alnico magnets have tended to be quite large to create sufficient magnetic pull; however, with the development of rare earth block magnets, that has changed, and rare earth block magnets are often the ideal choice.
The advantage of rare earth block magnets
As technology has demanded smaller and smaller parts, the demand for rare earth block magnets has grown. Rare earth block magnets are frequently created from neodymium, perhaps alloyed wit iron or boron. While these rare earth block magnets are available in different grades, they all offer greater magnetism in much smaller packages than would be possible with conventional magnets.
Does the grade matter?
When you start looking at rare earth block magnets, you will soon discover that there are multiple grades of rare earth magnets available. You must obtain the correct grade of the magnet for your application, or you could soon find that your product or piece of equipment soon stops working. It isn't enough to think about the strength of the magnet that you need. You will also need to think about where the magnet will be used and what the prevailing operating conditions will be. Lower grades of rare earth block magnets may initially be cheaper but if you find that they won't work in temperatures low enough for your requirements or that they don't have the right coating, or that they corrode too easily, then you are setting up your company for failure. If you aren't sure whether or not a particular magnet is right for you, then talk to your local supplier and ask them about their stock.
