Most standard neodymium magnets begin to lose magnetism at temperatures above 80∘C80 raised to the composed with power cap C 176∘F176 raised to the composed with power cap F
Common shapes include discs, rings, blocks, and spheres. You must also specify the magnetization direction (e.g., axially through the thickness or diametrically across the diameter) to ensure it works with your setup. Critical Safety Guidelines buy super magnets
When selecting a super magnet, several technical factors will determine its performance in your specific application: Most standard neodymium magnets begin to lose magnetism
Super magnets are not toys and can be extremely dangerous if handled incorrectly: Safety Standard for Magnets - Federal Register including nickel-copper-nickel (the most common)
Because neodymium magnets contain iron, they are highly prone to corrosion. Reliable suppliers like SuperMagnetMan offer various protective coatings, including nickel-copper-nickel (the most common), epoxy, or even gold.
