What Is Disc Neodymium Magnets?

It also known as round neodymium magnets or cylindrical neodymium magnets, are a type of permanent magnet made from neodymium, iron, and boron (NdFeB). They have a disc-shaped or cylindrical design, with the diameter being greater than the thickness.Neodymium magnets are known for their strong magnetic field and are considered the strongest commercially available magnets. They have a high energy density, which means they can generate a strong magnetic force relative to their size. This makes them suitable for a wide range of applications such as motors, sensors, magnetic therapy, magnetic closures, magnetic levitation, and more.Their strong attraction and small size make them very useful in various industries including automotive, electronics, medical, energy, and manufacturing. It's important to handle neodymium magnets with caution, as they can be quite powerful and may cause injuries or damage if mishandled.

Grade of Disc neodymium magnets

Disc neodymium magnets come in various grades, each denoted by a letter followed by a two-digit number. The letter represents the maximum energy product of the magnet, which is a measure of its magnetic strength. The higher the letter, the stronger the magnet.Here are some commonly available disc neodymium magnet grades:

N35: This is a lower grade magnet with a moderate magnetic strength. It is suitable for applications that do not require an extremely strong magnetic field.

N42: This is a medium-grade magnet with a stronger magnetic field than N35. It is commonly used in various industrial and commercial applications.

N52: This is a high-grade magnet with the strongest available magnetic strength. It is ideal for applications that require a very strong magnetic field, but it is also more expensive than lower grade magnets.

It's important to choose the appropriate grade for your specific application based on the desired magnetic strength and budget considerations.

Neodymium disc magnet features

Strong Magnetic Force: Neodymium magnets are the strongest permanent magnets available commercially. They generate a powerful magnetic field that can attract and hold objects several times their own weight.

Compact and Lightweight: Neodymium magnets have a high energy density, which means they can generate a strong magnetic force despite their small size and lightweight nature.

Wide Range of Sizes and Shapes: Neodymium disc magnets are available in various diameters, thicknesses, and shapes, allowing for customizable solutions to meet specific application needs.

Temperature Resistance: Neodymium magnets can withstand high temperatures, typically up to 80-200°C (176-392°F), depending on the grade. Special high-temperature grades are available for even higher temperature resistance.

Corrosion Resistance: Neodymium magnets are prone to corrosion, especially in humid or corrosive environments. To protect against corrosion, they are often coated with materials such as Nickel, Zinc, or Epoxy.

Versatility: Neodymium disc magnets are used in a wide range of applications, including electronics, motors, sensors, medical devices, magnetic separators, and DIY projects.

Relatively Low Cost: Despite their high magnetic strength, neodymium magnets are generally affordable, making them a cost-effective option for many applications.

Advantages & Disadvantages of Disc Neodymium Magnets


Maximum performance relative to size. Ideal for restricted space or compact applications.

Can be used in extremely cold conditions (e.g. in liquid nitrogen).

Standard Neodymium NdFeB Magnet is rated to +80 degrees C (176F) maximum. Can be rated to +100 (212F), +120 (248F), +150 (302F), +180 (356F), +200 (392F) and +220/230 degrees C (428/446F) with higher Hci versions.

High coercivity (Hci) to resist demagnetisation.

NxxT and L-NxxT alloys have better corrosion resistance than standard NdFeB but still needs coating.


Requires a protective coating to prevent the iron in the alloy from corroding (rusting).

NxxT and L-NxxT alloys are much more expensive and will still show signs of corrosion.

Higher temperature versions contain more Dy element increasing their cost.

Nd and Dy prices affect the production cost.

Above 150-180 deg C (302-356F), SmCo may be better.

Applications of Disc neodymium magnets


Magnetic Closure: Disc magnets are often used to create a magnetic closure mechanism in various products, such as purses, bags, jewelry, and clothing.

Magnetic Sensors: Disc magnets can be used in proximity sensors and reed switches to detect the presence or absence of magnetic fields, enabling their use in a wide range of applications, including security systems, automotive devices, and industrial machinery.

Magnetic Levitation: Disc magnets can be used in magnetic levitation systems, where the repelling force between magnets is utilized to suspend an object in mid-air.

Magnetic Separators: Disc magnets are commonly used in magnetic separation systems for removing ferrous contaminants from liquids or powders in industries such as food processing, pharmaceuticals, and mining.

Motors and Generators: Disc magnets are used in various types of motors and generators, including those found in automobiles, appliances, wind turbines, and robotics.

Magnetic Toys and Games: Disc magnets are often used in toys and games to create interactive magnetic experiences, such as building sets, puzzles, and educational toys.

Magnetic Jewelry: Disc magnets are popularly used in magnetic therapy and magnetic jewelry, believed to provide health benefits or as decorative elements in bracelets, necklaces, and earrings.

DIY Projects: Disc magnets are often used in various DIY projects, such as magnetic whiteboards, picture frames, magnetic knife holders, and magnetic hooks for organizing tools or other objects.
