Neodymium block & cube magnets come in various sizes and shapes, ranging from small, 1mm cubes to larger blocks measuring over 100mm in length. They can have a magnetic flux density of up to 1.4 tesla, which allows them to produce a strong magnetic field, making them ideal for a wide range of applications.
Neodymium block magnets are incredibly strong, with a magnetic field that can lift up to 1,000 times their own weight.
Custom neodymium block magnets offer several benefits to you, including high strength, durability, and the ability to maintain their magnetism over time. They can also be manufactured to precise specifications, allowing for greater design flexibility and increased efficiency in product assembly. Additionally, neodymium magnets are more cost-effective than other magnet types due to their high strength-to-weight ratio.
GP Magnets provides powerful, long lasting and inexpensive arc neodymium magnets for your motors and magnetic assemblies.

The magnetic direction distribution of neodymium block magnets refers to the way the magnetic field is oriented within the magnet. There are three main ways to distribute the magnetic direction of neodymium block magnets: axially and diametrically.
Axial magnetization is the most common configuration, where the magnetization runs along the length or axis of the block magnet. This configuration is ideal for applications where the magnet needs to have a strong pull force in a particular direction.
Diametrical magnetization is where the magnetization runs through the thickness or diameter of the block magnet. This configuration creates a strong magnetic field at the sides of the magnet and is useful for applications where the magnet needs to attract or repel in two directions.

Neodymium block magnets are the strongest type of permanent magnets, making them suitable for heavy-duty applications where high magnetic force is required.
NdFeB magnets are highly resistant to demagnetization and can retain their magnetic properties for a long time.
Due to their compact size, neodymium magnets can be used in a wide range of applications, including industrial, commercial, and consumer products.
Compared to other types of strong magnets, neodymium magnets are relatively inexpensive, making them a cost-effective solution for many applications.
Neodymium magnets have a high energy density, meaning they produce a strong magnetic field in a small space. This makes them ideal for applications where space is limited.
NdFeB magnets can be small in size yet still have high magnetic strength, which makes them useful in applications where space is limited.
