Rare Earth Block Magnet

Rare earth block magnet offer exceptional magnetic strength, capable of attracting metal objects much heavier than themselves. Rare earth block magnet maintains stable magnetic properties over long periods under normal temperature conditions. The cube shape of rare earth block magnet allows for even force distribution, greater contact area during adsorption, higher magnetic efficiency, and easy arrangement. They can be assembled into magnetic components of different sizes as needed, adapting to various scenarios.

Magnet Magnetization Direction

The magnetization direction of a magnet refers to the arrangement direction of the magnetic field inside the magnet, usually divided into axial magnetization and radial magnetization. The magnetization direction refers to the direction of the magnetic field inside the magnet, which determines the position of the north and south poles of the magnet. Different types of magnets (such as neodymium iron boron, ferrite, etc.) will have different directional choices during magnetization, which has a significant impact on their magnetic properties.

Regular Coating

Rare earth magnet coating materials have nickel, copper, chromium, gold, black zinc, epoxy resin, etc. The magnet coating is very thin, so it has almost no effect on the magnetic properties of the magnet. Coating can effectively reduce the sensitivity of magnets to oxygen and moisture, prevent oxidation and corrosion, and extend the service life of magnets.
