For most people, when they think of a magnet they think of a simple item that sticks to a refrigerator door, or a clasp that holds a piece of jewelry together. But there is a whole other world of magnets classified for industrial use. In fact, if you look around your home or office you’ll find a wide range of products that were produced or incorporated with an industrial magnet. These include everything from the speakers in your home audio/video system to the sensors in your automobile. Manufacturers have specific requirements on magnet types, sizes, compositions and strength, depending on use. Among the most frequently used industrial magnets are those made from neodymium and samarium cobalt, also known as rare earth magnets, ceramic (ferrite) magnets, electromagnets and alnico magnets.
