Due to specific properties, neodymium magnet MP 5x2.7/1.2x5 S / N38 in a ring form finds extensive use in various industries. Thanks to a powerful magnetic field of 0.56 kg, which can be described as lifting capacity, they are key in applications that require high magnetic power in a relatively small area. Applications of MP 5x2.7/1.2x5 S / N38 magnets include electrical mechanisms, generators, audio systems, and several other devices that use magnets for producing motion or storing energy. Despite their significant strength, they have a comparatively low weight of 0.62 grams, which makes them more practical compared to heavier alternatives.

Advantages and disadvantages of neodymium magnets NdFeB.

In addition to immense power, neodymium magnets have the following advantages:

They do not lose strength over time. After approximately 10 years, their power decreases by only ~1% (theoretically),
They are exceptionally resistant to demagnetization caused by an external magnetic field,
By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
They have very high magnetic induction on the surface of the magnet,
By using an appropriate combination of materials, they can achieve significant thermal resistance, allowing them to operate at temperatures up to 230°C and above...
Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in many variants of shapes or sizes, which enhances their versatility in applications.
Key role in the industry of new technologies – are utilized in HDD drives, electric drive mechanisms, medical devices or very highly developed apparatuses.

Disadvantages of neodymium magnets:

They can break when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and at the same time increases its overall strength,
High temperatures can reduce the power of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent loss in strength (although it is dependent on the form and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
Potential hazard associated with microscopic parts of magnets can be dangerous, when accidentally ingested, which becomes significant in the context of children's health. It's also worth noting that tiny parts of these magnets have the potential to hinder the diagnostic process after entering the body.

Exercise Caution with Neodymium Magnets

Neodymium magnets can become demagnetized at high temperatures.

Under specific conditions, Neodymium magnets may experience demagnetization when subjected to high temperatures.

Neodymium Magnets can attract to each other, pinch the skin, and cause significant swellings.

Neodymium magnets bounce and also clash mutually within a radius of several to around 10 cm from each other.

Neodymium magnets are among the strongest magnets on Earth. The surprising force they generate between each other can surprise 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.

You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.

Strong fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.

Maintain neodymium magnets away from children.

Neodymium magnets are not toys. Do not allow children to play with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.

Neodymium magnets are not recommended for people with pacemakers.

Neodymium magnets generate very strong magnetic fields that can 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.

The magnet coating is made of nickel, so be cautious if you have an allergy.

Studies clearly indicate a small percentage of people who suffer from metal allergies such as 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.

Dust and powder from neodymium magnets are flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.

Under no circumstances should neodymium magnets be brought close to 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 are extremely delicate, they easily break and can become damaged.

Neodymium magnets are characterized by significant fragility. 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 connection between the magnets, sharp metal fragments can be dispersed in different directions.

Please see the article - What danger lies in neodymium magnets? You will learn how to handle them properly.
