Ring magnets are a high demand product in today’s technologically advanced markets and are available in a variety of sizes, shapes and materials including neodymium, ferrite and samarium. Our production center specializes in the production of various grades of neodymium ring magnets (N, H, M and SH) with various coatings to enhance their resilience and functionality.
Ring Magnets with Holes
Ring magnets are round magnets with a hollow center. There are two hollow shapes available:
Regular Holes
Standard ring magnets are designed with the simplicity of a disc with holes strategically drilled to create concentric cavities. These standard hollow magnets are used in a wide variety of applications and some are even made in fairly large sizes, such as 250mm outer diameter and 200mm inner diameter. Smaller models are used in headphones, while larger models are used in speaker systems and the growing field of wall-climbing robots.
Counter-sunk Ring Magnets
Counter-sunk
Counter-sunk neodymium magnets have a dual feature design: one side is similar to a traditional ring magnet, while the other side is angled to form a countersunk recess, usually at 90 degrees, to fit tightly around a screw head. These particular magnets are often designed with a smaller central hole, which is attributed to their popularity in magnetic fishing, with the heaviest models boasting a lifting capacity of nearly a ton.
Strong Ring Magnets
For those seeking super strong magnetic force, there are two main options:
Size Up: Increase the size of the magnet to enhance the magnetic force, but at the expense of weight and volume.
Material Enhancement: Choose advanced materials such as neodymium or samarium cobalt to achieve lighter weight and greater magnetic force. Please note that these advanced magnets are expensive and have poor corrosion resistance.
Halbach Array Ring Magnets
Are you looking for something more powerful, such as those rated up to 1.6T (16,000 Gauss)? The Halbach Array is your magnet assembly solution, which provides amazing magnetic strength, although it is different from the traditional ring magnet configuration.
What are Ring Magnets Used For?
Ring magnets are widely used in a variety of fields due to their unique shape and magnetic properties. Here are some of the main uses:
Audio Equipment: Especially neodymium magnets, these round magnets are crucial in audio equipment such as speakers and hi-fi sound systems. They interact with electric currents and diaphragms to produce the sound vibrations we perceive.
Motors and Sensors: Ring magnets are used in a variety of motors and sensors, including those used in automotive and other technical applications. Their unique shape allows them to interact effectively with other components, making them a great fit.
Science Experiments and Demonstrations: In educational settings, ring magnets help demonstrate the principles of magnetism. They are often used to visually demonstrate the repelling properties of like magnetic poles.
Manufacturing and Fixturing Applications: Ring magnets are widely used in different production workflows and fixture tasks, and are flexible and adaptable due to their ability to fit seamlessly onto cylindrical structures.
Magnetic Therapy: Some people believe that wearing ring magnets as jewelry can have health benefits. Theory suggests that magnets can improve blood circulation, reduce inflammation, and promote overall health. However, it is important to note that there is limited scientific evidence to support these claims.
Mechanical Attachments: For requirements that require a reliable mechanical fixation method, round magnets are the preferred choice due to their inherent ability to easily fit onto a rod or tube.
