This is defined in Mega Gauss Oersteds, or MGOe. The strength of a magnet can be found in the magnet specification known as BHmax, which is the maximum energy density of a magnet. There are several factors and considerations that go into design, but for this article, the areas discussed will be Magnets Strength, Magnet Coercivity, and the Considerations for Magnet Selection. Neodymium Magnets and Samarium Cobalt Magnets are available in many grades. While these are only a few of the questions we could ask, this may lead to other questions about operating environments and options. Are there specific coating requirements?.Is the magnet in an assembly or operating independently?.What is the size of the area for the magnet?.steel, aluminum, plastic, etc.) will the magnet be next to? What is the temperature that the magnet will be exposed (maximum operating temperature)?.If this is the situation, we will then ask such questions as: But, in about 50% of the situations, our customers are not able to make known the application due to Confidentiality and Privacy reasons. This helps us understand the environment and requirements of the magnet. When we assist customers with magnet selection we will undoubtedly ask questions about the application. We will focus specifically on the strongest rare earth magnets available, neodymium magnets (NdFeB) and samarium cobalt (SmCo) magnets.Ĭlick Here to Buy Magnets Online at SuperMagnetMan This article will try to simplify how magnets are designated, and define the differences between magnet grades. Neodymium Magnets, Samarium Cobalt (SmCo) Magnets, Ceramic Magnets, Alnico Magnets, Bonded Magnets, and Injection Molded Magnets all have various options, and choosing the correct grade for your application is critical. Understanding Magnet Grades and Magnet TablesĮach day we get asked questions about the differences in magnetic materials.
