Neodymium magnets MP 5x1.5x3 / N38 in a ring-shaped form are regularly used in various industries due to their unique properties. Thanks to a powerful magnetic field of 0.56 kg, which can be described as force, they are key in applications that require high magnetic power in a relatively small area. Applications of MP 5x1.5x3 / N38 magnets include electrical mechanisms, generating systems, audio systems, and several other devices that use magnets for producing motion or energy storage. Despite their powerful strength, they have a relatively low weight of 2.47 grams, which makes them more practical compared to heavier alternatives.

The operation of ring magnets results from their unique atomic structure. Their properties arise from a controlled production process, including sintering and magnetization, which allows for the creation of a concentrated magnetic field in a specific direction. This makes them perfect for devices such as stepper motors or industrial robots. Additionally, ring magnets are resistant to demagnetization.

Ring magnets have a wide range of applications in many industries, such as production of electronic devices, such as speakers and electric motors, automotive, where they are used in brushless electric motors, and medical equipment, e.g., in scanning devices. Their ability to work in high temperatures and precise magnetic field control makes them indispensable in challenging industrial conditions.

Their uniqueness comes from extraordinary pulling power, resistance to high temperatures, and precision in generating the magnetic field. Their unique ring form allows for application in devices requiring concentrated magnetic fields. Moreover, these magnets are significantly stronger and more versatile than ferrite counterparts, making them an ideal choice in the automotive, electronics, and medical industries.

Ring magnets perform excellently across a wide range of temperatures. Their magnetic properties remain stable, as long as the temperature does not exceed the Curie point. They are more resistant to loss of magnetism than traditional ferrite magnets. Because of this, they are ideal for applications in the automotive industry, robotics, and devices requiring operation in changing or extreme environmental conditions.

A ring magnet of class N52 and N50 is a powerful and highly strong magnetic product designed as a ring, that offers strong holding power and universal application. Attractive price, 24h delivery, ruggedness and broad range of uses.

Advantages as well as disadvantages of neodymium magnets NdFeB.

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They retain their full power for nearly ten years – the drop is just ~1% (according to analyses),
They remain magnetized despite exposure to magnetic surroundings,
By applying a reflective layer of nickel, the element gains a clean look,
Magnetic induction on the surface of these magnets is impressively powerful,
Neodymium magnets are known for exceptionally strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the magnetic form),
With the option for customized forming and precise design, these magnets can be produced in multiple shapes and sizes, greatly improving engineering flexibility,
Wide application in advanced technical fields – they serve a purpose in data storage devices, electromechanical systems, healthcare devices along with technologically developed systems,
Thanks to their concentrated strength, small magnets offer high magnetic performance, while occupying minimal space,

Disadvantages of neodymium magnets:

They can break when subjected to a heavy impact. If the magnets are exposed to physical collisions, we recommend in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from cracks , and at the same time increases its overall robustness,
High temperatures may significantly reduce the holding force of neodymium magnets. Typically, above 80°C, they experience permanent loss in performance (depending on form). To prevent this, we offer heat-resistant magnets marked [AH], capable of working up to 230°C, which makes them perfect for high-temperature use,
They rust in a wet environment. If exposed to rain, we recommend using waterproof magnets, such as those made of plastic,
Limited ability to create precision features in the magnet – the use of a external casing is recommended,
Potential hazard due to small fragments may arise, if ingested accidentally, which is crucial in the health of young users. It should also be noted that minuscule fragments from these products can interfere with diagnostics after being swallowed,
In cases of mass production, neodymium magnet cost may not be economically viable,

Notes with Neodymium Magnets

Magnets are not toys, children should not play with them.

Neodymium magnets are not toys. Do not allow children to play with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times stronger, and their power can shock you.

On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.

Magnets made of neodymium are incredibly delicate, they easily crack as well as can become damaged.

Neodymium magnetic are extremely fragile, and by joining them in an uncontrolled manner, they will crumble. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. At the moment of collision between the magnets, small metal fragments can be dispersed in different directions.

Neodymium magnets are not recommended for people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.

Keep neodymium magnets as far away as possible from GPS and smartphones.

Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.

Neodymium Magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant injuries.

If have a finger between or on the path of attracting magnets, there may be a serious cut or a fracture.

Neodymium magnets can demagnetize at high temperatures.

Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.

The magnet is coated with nickel - be careful if you have an allergy.

Studies show a small percentage of people have allergies to certain metals, including nickel. An allergic reaction often manifests as skin redness and rash. If you have a nickel allergy, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Do not place neodymium magnets near a computer HDD, TV, and wallet.

Neodymium magnets generate intense magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
