Rectangular NdFeB (Neodymium Iron Boron) magnets are a type of high performance permanent magnet that is rectangular or square in shape and made from a neodymium alloy. NdFeB magnets are the strongest type of permanent magnet known and have a wide range of applications due to their strong magnetic properties and compact size.
Material Composition:
These magnets are made from a combination of neodymium (Nd), iron (Fe) and boron (B) and are commonly referred to as NdFeB or neodymium magnets.
The material is sintered or bonded to achieve high magnetic strength.
Magnetic Strength:
Rectangular NdFeB magnets have extremely high magnetic strength relative to their size. For example, the N52 grade magnets have one of the highest energy products and can provide a magnetic field strength of up to 1.4 Tesla.
These magnets are axially magnetized, which means that their magnetic poles are located on the larger rectangular surface.
Available in a range of dimensions, from very small (a few millimeters) to larger magnets, allowing for versatility across different applications. Common sizes include 20×10×5mm, 50×25×10mm, or custom sizes based on user needs.
NdFeB magnets come in various grades, with N35, N42, N50, and N52 being the most common. The higher the grade, the stronger the magnetic field.
Standard NdFeB magnets can operate in temperatures up to 80°C (176°F), while specially designed variants can handle higher temperatures without significant loss of magnetism.
Rectangular NdFeB magnets are among the most powerful magnets currently in use, offering excellent magnetic strength in a compact, flat form. They are used in a wide range of industrial, technical and everyday applications and are indispensable magnets in everything from motors to sensors to magnetic mounts and closures.

The rectangular shape provides a larger contact surface, which increases holding force in applications that require strong surface contact, such as magnetic mounting and fixing solutions.
The magnetic field is distributed across the length and width of the magnet, making rectangular NdFeB magnets ideal for applications that require strong, evenly distributed magnetic force.
Rectangular magnets can be cut to specific sizes, making them highly customizable for industrial or personal projects.
Customized square magnets are usually used for industrial purposes or in some more sophisticated processes. Customers customize the size of the magnets through product customization. Of course, our quadrilateral magnets are also used in some daily aspects.
