Developing high performance magnets requires understanding and managing coercivity. Coercivity in a magnetic material is a measure of whether it is able to resist an outside magnetic field and/or high temperatures without losing magnetism. To learn more read our blog article, "Understanding Magnet Grades and Magnet Tables." Our wide selection of neodymium high coercivity magnets gives you much to choose from, however if you require a specific size that is not available on our website, please contact us or fill out our custom magnet request form.
