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
The strength of a neodymium magnet is indicated by its grade, typically ranging from N30 to N52 . A higher number signifies a stronger magnetic field and greater "adhesive force".

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.
