Shopping tips

Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their remarkable pulling force, neodymium magnets offer the following advantages:
- They do not lose their even during around ten years – the decrease of lifting capacity is only ~1% (theoretically),
- They are very resistant to demagnetization caused by external magnetic fields,
- Thanks to the glossy finish and gold coating, they have an elegant appearance,
- Magnetic induction on the surface of these magnets is notably high,
- They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
- With the option for tailored forming and personalized design, these magnets can be produced in various shapes and sizes, greatly improving application potential,
- Important function in cutting-edge sectors – they are utilized in data storage devices, rotating machines, clinical machines or even high-tech tools,
- Thanks to their power density, small magnets offer high magnetic performance, with minimal size,
Disadvantages of rare earth magnets:
- They are prone to breaking when subjected to a heavy impact. If the magnets are exposed to physical collisions, it is suggested to place them in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from cracks and additionally strengthens its overall resistance,
- Magnets lose power when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible field weakening (influenced by the magnet’s profile). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
- Magnets exposed to wet conditions can oxidize. Therefore, for outdoor applications, we suggest waterproof types made of rubber,
- The use of a protective casing or external holder is recommended, since machining threads in neodymium magnets is difficult,
- Safety concern related to magnet particles may arise, especially if swallowed, which is important in the health of young users. Furthermore, tiny components from these devices can hinder health screening when ingested,
- In cases of tight budgets, neodymium magnet cost may be a barrier,
Safety Precautions
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.
Neodymium magnets are the most powerful magnets ever invented. Their power 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.
Neodymium magnets can demagnetize at high temperatures.
Despite the general resilience of magnets, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
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.
Magnets may crack or crumble with careless joining to each other. Remember not to move them to each other or have them firmly in hands at a distance less than 10 cm.
Neodymium magnets should not be in the vicinity 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.
Never bring neodymium magnets close to a phone and GPS.
Neodymium magnets are a source of intense magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
The magnet is coated with nickel. Therefore, exercise caution 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
People with pacemakers are advised to avoid neodymium magnets.
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.
Neodymium magnetic are fragile and can easily break as well as shatter.
Neodymium magnets are characterized by considerable fragility. Magnets made of neodymium are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of collision between the magnets, sharp metal fragments can be dispersed in different directions.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
Strong magnetic fields emitted by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.
Pay attention!
