It is crucial to select neodymium magnets of the appropriate force for the intended application, and to check the compatibility of the cover for the working environment, in order to ensure optimal performance and safety.

Advantages and disadvantages of neodymium magnets NdFeB.

Apart from their superior magnetism, neodymium magnets have these key benefits:

Their strength is durable, and after around 10 years, it drops only by ~1% (theoretically),
They remain magnetized despite exposure to magnetic surroundings,
In other words, due to the metallic nickel coating, the magnet obtains an aesthetic appearance,
The outer field strength of the magnet shows advanced magnetic properties,
They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
Thanks to the possibility in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in various configurations, which broadens their usage potential,
Important function in new technology industries – they are utilized in HDDs, rotating machines, diagnostic apparatus and high-tech tools,
Compactness – despite their small size, they provide high effectiveness, making them ideal for precision applications

Disadvantages of NdFeB magnets:

They may fracture when subjected to a heavy impact. If the magnets are exposed to external force, it is advisable to use in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from damage and additionally strengthens its overall resistance,
They lose field intensity at high temperatures. Most neodymium magnets experience permanent reduction in strength when heated above 80°C (depending on the shape and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
They rust in a moist environment – during outdoor use, we recommend using moisture-resistant magnets, such as those made of non-metallic materials,
The use of a protective casing or external holder is recommended, since machining multi-axis shapes in neodymium magnets is risky,
Possible threat from tiny pieces may arise, if ingested accidentally, which is significant in the family environments. Moreover, tiny components from these devices can complicate medical imaging if inside the body,
In cases of tight budgets, neodymium magnet cost is a challenge,

Exercise Caution with Neodymium Magnets

It is essential to maintain neodymium magnets away from children.

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.

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 are fragile and can easily crack as well as get damaged.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.

Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.

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

Dust and powder from neodymium magnets are highly flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

Neodymium magnets can demagnetize at high temperatures.

Under specific conditions, Neodymium magnets can lose their magnetism when subjected to high temperatures.

Avoid contact with neodymium magnets if you have a nickel 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

Neodymium magnets are the strongest magnets ever created, and their power 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.

Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.

Magnets will attract each other within a distance of several to around 10 cm from each other. Don't put your fingers in the path of magnet attraction, as a serious injury may occur. Depending on how massive the neodymium magnets are, they can lead to a cut or alternatively a fracture.
