Neodymium Disc Magnets

Table of Contents

Neodymium disc magnets are good choices for applications in consumer products and industrial products, thanks to their excellent magnetic performances and cost-effectiveness.

Neodymium disc magnets are one of the most commonly used types of strong magnets in the market. They are an important component of the manufacturing sector. Their common applications include electric motors, speakers, sensors, etc.

Osenc is a custom neodymium magnet supplier. And we can offer neodymium disc magnets in various thicknesses and sizes. Meanwhile, there are also multiple coatings for you to choose from – zinc, nickel, silver, gold, epoxy, etc.

Features of neodymium disc magnets

Neodymium disc magnets have a round shape, whose diameters are bigger than their thickness. They have high magnetism, small dimensions, smooth surfaces, and large magnetic areas, which are common features of this shape. They are an important consideration for designing and manufacturing consumer, industrial, scientific and medical products.

Dimensional identification

As a common practice, neodymium magnet manufacturers use 2 parameters to define the sizes of disc neodymium magnets.

They are the diameter and thickness (height), usually with numbers in millimeters.

Suppose you are looking for a disc neodymium magnet with a diameter of 9 mm and a height of 3 mm, you can specify it this way: D9 x 3 mm.

Using this dimensional identification for custom neodymium magnets will help eliminate unnecessary misunderstandings on both sides about dimensions.


Neodymium magnets have different grades, ranging from N35 to N55, and they also have high-temperature designs for special applications.

You can refer to our introduction to neodymium magnet grades. It will be helpful for you to determine which grade is the most appropriate for you.

Magnetization directions

Disc Magnet Axially Disc Magnet Diametrically

Disc neodymium magnets have 2 common magnetization directions. They are the axial and radial magnetization directions.

Meanwhile, they still have 2 additional possible magnetization directions, though they are not commonly applied.


Optional designs

Adhesive Backed Magnets

With adhesive

The adhesive magnet has double-sided tape on its back. You can stick those magnets to a variety of surfaces. And there can be different types of double-sided tapes, which are designed for various applications.  

countersunk neodymium magnets

Countersunk neodymium magnets 

Countersunk magnets have a hole in the center of the disc. It is for inserting a screw for fastening or positioning. Such a design is ideal for applications like hanging signs, tools, posters, etc. And particularly for cabinets, kitchens, booths, stores, etc.

neodymium ring magnets

We usually call them ring magnets. This is the most common shape on the market. That is disc magnet with a straight hole.
