Diameter (Inner/Outer) 1mm - 10mm

AMF Magnets is a leading magnet supplier with a fantastic range of small magnets. We provide customers with high-quality magnetic products such as neodymium magnets at very competitive prices. This range includes small disc magnets, ring magnets and cylinder magnets with a diameter between 1mm and 10mm. Most of the magnets in this category are Neodymium magnets, this is due to their high-power magnetic strength. The magnetic energy product of a Rare Earth magnet is 10 times that of a Ferrite, the next strongest form of permanent magnet.

Neodymium magnets

Neodymium magnets are the most widely-used type of rare-earth magnets. Neodymium magnets are in fact an alloy of Neodymium, Iron, and Boron. These magnets are the strongest type of permanent magnet available. However there are a couple of drawbacks to using Neodymium magnets that should be considered in relation to each customer’s application.
Standard N32-N35 grade Neodymium magnets have a maximum operating temperature of 80℃. If rare earth magnets are exposed to temperatures above this they will begin to weaken. If the exposure is prolonged the magnet will be permanently damaged. However there are a number of specialty grades denoted by the S or SH letters added to the N prefix of the magnet grade. These increase the operating temperature of the magnet, depending on the particular grade this varies with the highest being 150℃.

Choosing the best small magnet shape

There are a number of things to consider when choosing the ideal magnet, fit for purpose. Along with the type of magnet and the strength of the magnet, each individual application calls for consideration of the best shape of magnet. In this category of 1mm-10mm diameter magnets you will find ring magnets, cylinder magnets and disc magnets. Each of these shapes comes with its own attributes that make it well suited to particular circumstances or environments.

If you are looking for a magnet that can be easily slotted onto a shaft or secured with wire or thread, a Ring magnet is perfect. The central hole provides the opportunity to attach this magnet to a non ferrous material without using an adhesive.
Cylinder magnets have more magnetic material between the two poles and this gives them are more concentrated and penetrating magnetic field. Cylinder magnets are well suited to applications that require precision and are often used as component parts of moving mechanical apparatus for this reason.

Disc magnets are certainly one of the most ubiquitous shapes of magnets. Their flat aspect means they can be incorporated into product designs without compromising on the look of the finished product. These thin magnets can be found in all sorts of electronic goods around the home or office. In recent years there has been a surge in popularity of product designers using small magnetic discs or thin blocks to create magnetic clasps in leather goods, laptops, phone holders and much more.

The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More
