Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to their exceptional magnetic power, neodymium magnets offer the following advantages:
- They have stable power, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
- They protect against demagnetization induced by surrounding electromagnetic environments very well,
- Because of the reflective layer of silver, the component looks visually appealing,
- The outer field strength of the magnet shows advanced magnetic properties,
- These magnets tolerate extreme temperatures, often exceeding 230°C, when properly designed (in relation to profile),
- Thanks to the freedom in shaping and the capability to adapt to specific requirements, neodymium magnets can be created in different geometries, which increases their functional possibilities,
- Significant impact in advanced technical fields – they find application in computer drives, rotating machines, clinical machines along with technologically developed systems,
- Compactness – despite their small size, they generate strong force, making them ideal for precision applications
Disadvantages of neodymium magnets:
- They are prone to breaking when subjected to a powerful impact. If the magnets are exposed to shocks, we recommend in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from cracks and reinforces its overall strength,
- Magnets lose magnetic efficiency when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible power drop (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 degrade. Therefore, for outdoor applications, we suggest waterproof types made of plastic,
- The use of a protective casing or external holder is recommended, since machining multi-axis shapes in neodymium magnets is not feasible,
- Potential hazard from tiny pieces may arise, especially if swallowed, which is notable in the protection of children. Additionally, miniature parts from these assemblies may hinder health screening after being swallowed,
- In cases of tight budgets, neodymium magnet cost may not be economically viable,
Handle Neodymium Magnets with Caution
Neodymium magnets are known for their fragility, which can cause them to crumble.
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. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.
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.
You should keep neodymium magnets at a safe distance from the wallet, computer, and TV.
The strong magnetic field generated by neodymium magnets can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.
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.
If have a finger between or alternatively on the path of attracting magnets, there may be a severe cut or a fracture.
Keep neodymium magnets away from 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. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.
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.
Never bring neodymium magnets close to a phone and GPS.
Neodymium magnets generate strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
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.
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.
Magnets should not be treated as toys. Therefore, it is not recommended for youngest children to have access to them.
Remember that neodymium magnets are not toys. Be cautious and make sure no child plays with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.
