It is important to keep the magnetic beads away from young kids, because the small pieces can be accidentally ingested, which creates a serious risk.

Advantages and disadvantages of neodymium magnets NdFeB.

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

They do not lose their power (of the magnet). After about 10 years, their strength decreases by only ~1% (theoretically),
They protect against demagnetization caused by external magnetic field extremely well,
In other words, thanks to the glossy nickel, gold, or silver finish, the element gains an visually attractive appearance,
They possess very high magnetic induction on the surface of the magnet,
Thanks to their high temperature resistance, they can operate (depending on the shape) even 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 a wide range of shapes and sizes, which enhances their versatility in applications.
Significant importance in advanced technologically fields – are used in hard drives, electric motors, medical equipment or other advanced devices.

Disadvantages of neodymium magnets:

They are prone to breaking as they are extremely fragile when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
Magnets lose their power due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent reduction in strength (although it is worth noting that this is dependent on the shape and size of the magnet). To avoid this problem, we offer special magnets marked with the [AH] symbol, which exhibit high temperature resistance. They can operate even at temperatures as high as 230°C or more,
Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
Health risk associated with microscopic parts of magnets are risky, when accidentally ingested, which is crucial in the context of children's health. Additionally, tiny parts of these devices can be problematic in medical diagnosis in case of swallowing.

Handle Neodymium Magnets with Caution

It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.

In the case of holding a finger in the path of a neodymium magnet, in that situation, a cut or a fracture may occur.

The magnet is coated with nickel. Therefore, exercise caution 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.

Keep neodymium magnets away from TV, wallet, and computer HDD.

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.

Magnets made of neodymium are extremely delicate, they easily fall apart as well as can crumble.

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 collision between the magnets, small metal fragments can be dispersed in different directions.

Neodymium magnets can become demagnetized 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.

It is essential to keep neodymium magnets away from youngest children.

Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.

Do not bring neodymium magnets close to GPS and smartphones.

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets should not be near people with pacemakers.

In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes with the operation of a heart pacemaker. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

Neodymium magnets are the most powerful magnets ever created, and their strength can surprise you.

Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.

Be careful!
