Neodymium Bar Magnets

Neodymium bar magnets (also known as rectangle magnets, as they are comparable to neodymium block magnets) have consistent cross-sections much smaller than their widths. They can be round, square, hexagonal, octagonal, or rectangular.

Neodymium Bar Magnets

Neodymium bar magnets (also known as rectangle magnets, as they are comparable to neodymium block magnets) have consistent cross-sections much smaller than their widths. They can be round, square, hexagonal, octagonal, or rectangular.

Using conventional methods, producing bar-shaped neodymium magnets is reasonably straightforward. This can improve the efficiency and cost-effectiveness of the production process. As a result, they are a diverse and adaptable choice for your product ideas and manufacturing.

Features Of Neodymium Bar Magnets

Neodymium Bar Magnets can generate a strong, homogeneous magnetic field. As a result, they are a feasible choice for a wide variety of uses, including market products, industrial apparatus, medical equipment, and so on.

They are simple to incorporate into current product and equipment designs. For example, you can place a bar-shaped magnet on a frame or clamp and use it with other components to create a magnetic assemblage.

Theoretically, it is easier to create Neodymium Bar Magnets to the desired length using normal equipment, which is less expensive and less likely to have quality problems.

Organize Neodymium Bar Magnets in a particular design to make unique magnetic fields. This trait is helpful for uses where a single giant magnet is not accessible or would be prohibitively expensive.

In a nutshell, Neodymium Bar Magnets can provide design freedom and utility for a variety of applications. Magnet rods have numerous uses. Common examples include:

Tools, blades, and other metal items should be organized on a workbench or a tool shelf.

Reinstall the screws and fasteners that hold the product components together.

Protected openings and entrances, for example, in businesses and classrooms

Provide a magnetic force for science studies or medicinal procedures

Magnet bars are commonly used in these and other uses due to their relative power, longevity, and usefulness.

Dimensional Identifications

By default, we use metric units of measurement for sizes, and imperial units of measurement are only used for clarity. If there are slight variations, use metric measures for proof.

The dimension for Neodymium Bar Magnets: Length x Width x Height

Usually, the dimension begins with an uppercase letter F.

If a neodymium magnet bar has a dimension of F90 × 3 × 2 mm, its length is 90 mm, the width is 3 mm, and the height is 2 mm.

Magnet bar: Length x Width x Height (For example, F90 x 7 x 5 mm)

Magnet bar with a hole: Length x Width x Height x Hole diameter (For example, F90 x 7 x 7 x D3 mm)

Magnet bar with a countersunk hole: Length x Width x Height x Major hole diameter (For example, F90 x 7 x 7 x M3 mm)

Available Dimensions

The specifications offered for Neodymium Bar Magnets are identical to those for Neodymium Bar Magnets. Their primary distinctions are their forms and use.

Available Sizes

Length: 1 – 254mm (1/16 – 10 inches)

Width: 0.5 – 127mm (1/64 – 5inches)

Height: 0.3 – 120mm (1/64 – 4 ¾ inches)

The Largest Neodymium Bar Magnets

Rectangle: Length 254 × width 80 × height 50mm (10 x 3 1/8 x 1 15/16 inches)

Square: Length 100 × width 100 × height 60mm (3 15/16 x 3 15/16 x 2 3/8 inches)

The longest magnetization direction: 200mm (7 7/8 inches)


If one route has the most important measurement, the other orientations should have lesser sizes.

The width should not be too thin if the proportions of the two orientations are more significant.

The Smallest Neodymium Bar Magnets

The smallest size we can make is 1×1 × 0.3mm (1/16 x 1/16 x 1/64 inches). That is a micro neodymium magnet, very tiny.


The purity of its magnetic field determines the strength of a neodymium magnet. A number represents the grade of a neodymium magnet. A higher figure indicates a stronger magnetic field.

Neodymium magnets come in various grades spanning from N35 to N55 and high-temperature categories for specific uses such as H, M, SH, EH, and AH.

You can learn more about neodymium magnet classes by reading our primer. It will assist you in determining which school level is best for you.


At work, neodymium magnets are responsive to their environment. They may degrade quickly due to moisture and other acidic substances.

To improve the durability of neodymium magnets, we will need to apply a layer, or possibly multiple layers, of compounds to their surfaces. As a consequence of the coverings, the magnets will be more immune to fractures and other types of harm.

We can make bespoke neodymium magnets with a variety of finishes. Nickel, copper, urethane, and other materials are among them. Each of them has distinct characteristics and advantages.

Magnetization Directions

As a common practice, the size identification for magnet bars: Length x Width x Height.

The last digit of this size identification is the magnetization direction.

For example, for a magnet bar with the identification of F20 x 15 x10 mm, the magnetization direction of this magnet is 10 mm.
