Nd is a chemical element with the symbol Nd and atomic number 60. It is a soft, silvery metal that tarnishes in air. It is abundant in the minerals monazite and bastnäsite, which are found in fluoroc...
Rare earth magnets are strong permanent magnets made up of rare earth alloy elements. Research on rare earth magnets began in the 1970s and 1980s. Among permanent magnets, rare earth magnets can gener...
Strong Rare Earth Neodymium Rectangular Magnets
The square magnet blocks are known as rectangular(rectangle) magnets.The same as disc,ring and rod magnet,rectangular magnets are also important and popular industry magnets. All rectangular（square or block) magnets in this category made of rare earth neodymium material, which are known as strong rectangular magnets. We just show some popular square neodymium magnets in this category, which are the best seller for most of magnet distributors, with strong processing ability, we can also customize some special square neodymium magnets for customers, contact us for customer neodymium rectangular magnets!
Small-sized rare earth neodymium block magnets of 6x4x2mm
6x4x2mm neodymium are earth magnet blocks with nickel coating
10x10x1mm thin rare earth neodymium block magnets with nickel coated
Square permanent magnets of rare earth neodymium 10x10x1mm
Powerful square neodymium magnets with dimension of 10x10x3mm
10x10x3mm nickel coated rare earth neodymium block magnets N42
Rare earth neodymium rectangular(block)magnets are usually specified by three dimensions (length,width,and thickness), the front two dimensions detail the size of each magnet pole,because most of rectangular neodymium magnets are magnetized through thickness.
The power of neodymium rectangular(block) magnets ranges from N35 to N52,N52 is the strongest rectangular rare earth neodymium magnets.
Neodymium rectangular(block) magnets have widest size range,which range from 1mm tiny neodymium magnets to 250mm super big neodymium magnets
Square neodymium magnet blocks are not waterproof magnets,which need surface treatment protection.
Super strong rectangular neodymium magnets are dangerous!Two rectangular rare earth neodymium magnets attract each other with almost twice force as much as they attract steel objects. They even attract each other through a very long distance. Even small rectangular neodymium magnets attract each other through the thickness of you fingers.Big or large rectangular neodymium magnets have super strong force,any improper operation can cause injury to fingers.

Applications of neodymium(rare earth) rectangular magnets.Because of the advantages of small size and strong magnetic force, neodymium rare earth rectangular magnets are given a wide range of applications. They can be fixed in a proper position with adhesive or embedded in wood or plastic slots.High property neodymium rare earth rectangle magnets are used in applications such as motor, medical,separator research, sensor, wind-power.....
Simply speak,square neodymium magnets are made out by steps of sintering,cutting.Small square&rectangular neodymium magnets are got by cutting from bigger neodymium magnet blocks.Surface treatment is needed for applied neodymium magnets,because they are not corrosion resistant.
Rare earth rectangular magnets are usually known as strong type rectangle magnet,for a certain size,the strongest and most powerful square(rectangular) magnet on the earth must be made of rare earth neodymium.
A rectangular shaped neodymium magnet block are expressed with length,width and thickness, for example: L x W x T
