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
Buying "super magnets"—primarily rare-earth magnets—requires balancing extreme power with specific safety and technical constraints. These magnets are the strongest permanent magnets available, capable of holding thousands of times their own weight. Key Buying Considerations buy super magnets
Super magnets are not toys and can be extremely dangerous if handled incorrectly: Safety Standard for Magnets - Federal Register Most standard neodymium magnets begin to lose magnetism
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. When selecting a super magnet, several technical factors
). For high-heat environments like automotive engines, look for specialized grades with higher temperature tolerances, such as those doped with dysprosium.
When selecting a super magnet, several technical factors will determine its performance in your specific application:
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
