Neodymium disc magnets are small, highly powerful magnets made from an alloy of neodymium, iron, and boron. These magnets belong to the rare-earth magnet family and are known for their exceptional magnetic strength and resistance to demagnetization compared to other types of magnets, such as ferrite or alnico magnets. They typically appear in a disc shape, which maximizes their magnetic field strength on the flat circular surfaces. Neodymium disc magnets are widely used in various applications including electronics, automotive, medical devices, and clean energy solutions. Their compact size and strong magnetic force make them ideal for miniaturized and space-constrained applications. However, they are brittle and prone to corrosion, often requiring protective coatings to maintain their performance and durability.
