Small Cylinder Magnet [Size Shape Uses Magnetized]

Small Cylinder Magnet is one of the more popular magnet types in the market, it has small (tiny) diameter, it is very much used in toys and ornaments, magnetic tools and accessories, sensors, electronic products, its size, shape type, magnetization method, etc. All of them determine its performance and usage scenarios, the following is a detailed introduction of small cylinder Magnet.

The following pictures show tiny cylinder neodymium (rare earth) magnets.

Minimum size of small cylindrical magnets

The size of small cylindrical magnets can be very tiny, usually from 0.5mm to 5mm in diameter, and the height can also be made very thin, such as 0.5mm, 1mm, 2mm, 3mm 10mm.

Types of small cylindrical magnets

According to the different production process, material and magnetic force, small cylindrical magnets can be divided into small cylindrical neodymium magnets, small ferrite cylindrical magnets, small samarium cobalt cylindrical magnets. Among them, NdFeB material is the most common, with very high magnetic energy product and magnetic field strength. Ferrite material has weaker magnetic force and lower cost, which is suitable for occasions with less stringent requirements on magnetic force. Samarium cobalt material is slightly weaker than NdFeB magnet, but has better high temperature resistance and corrosion resistance, suitable for harsh environments.

Small cylindrical magnets according to the type of form can be divided into standard cylindrical (rod), cylinder magnets with holes, but also some customers will require slotted (this is less), that is, slotted cylindrical magnets.

The magnetization direction of small cylindrical magnet;

Mainly axial and radial magnetization, axial magnetization strong magnetic surface (use surface) in the upper and lower 2 end surfaces, radial magnetization strong magnetic surface (use surface) in the side, detailed explanation, please see“ Axially magnetized vs diametrically magnetized ”.

Typical applications of small miniature cylindrical magnets;

Small cylinder magnets are also used in certain small medical devices, such as magnetic attractors for surgery and magnetic implants.

Small cylindrical magnets are commonly used in Hall sensors, displacement sensors, etc. in precision measuring instruments as sensing elements or as part of the working principle.

Small cylinder magnets are used for adjusting the positioning of optical elements, stabilizing equipment, and so on.

In some traditional ammeters and voltmeters, small cylindrical magnets are used to generate a stable magnetic field to control the deflection of the pointer.

Magnetic flow meters use small cylindrical magnets to generate a fixed magnetic field to help measure the flow of a fluid.

Many magnetic puzzles, educational toys (e.g. magnetic blocks, magnetic balls, etc.) use small cylindrical magnets because they can be easily attached and connected.

Some photo frames use small cylindrical magnets to hold photos in place, allowing them to be easily changed.

These applications utilize the small size, high magnetic force, and magnetic stability of small cylindrical magnets for a variety of applications that require small, precise magnets.

Selection aspect, you need to choose the right magnet based on the magnetic requirements of the usage scenario. For example, some devices require very strong magnetism, while others only require weaker magnetism. The performance of magnets from different materials varies greatly, and factors such as magnetic force, temperature resistance and corrosion resistance need to be considered when selecting. If the application scenario has high temperature or humidity, it is better to choose high temperature resistant or waterproof magnet material, such as samarium cobalt, ferrite.
