NdFeB Magnet, also known as neodymium magnet or rare earth magnet, is a type of high-performance permanent magnet made from an alloy of neodymium, iron, and boron. It is the strongest type of permanent magnet available commercially, with a maximum energy product of up to 52 MGOe (MegaGauss Oersted). NdFeB magnets are widely used in various industrial and commercial applications due to their super strong magnetic properties.
The magnetism direction of our NdFeB magnets is through the thickness, also known as axially. This means that the north and south poles are located on opposite sides of the magnet, making it ideal for applications where a strong holding force is required in a specific direction.
In conclusion, NdFeB Magnet is a super strong magnet with high coercivity and high energy product, making it an ideal choice for a wide range of industrial and commercial applications. With our large inventory, ODM services, and flexible processing options, we are committed to providing high-quality NdFeB magnets that meet the unique needs of our customers.
