Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to their tremendous magnetic power, neodymium magnets offer the following advantages:
- They virtually do not lose power, because even after 10 years, the decline in efficiency is only ~1% (according to literature),
- They remain magnetized despite exposure to magnetic noise,
- By applying a shiny layer of gold, the element gains a modern look,
- They possess significant magnetic force measurable at the magnet’s surface,
- Neodymium magnets are known for exceptionally strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the geometry),
- With the option for fine forming and personalized design, these magnets can be produced in various shapes and sizes, greatly improving engineering flexibility,
- Wide application in new technology industries – they find application in HDDs, electric drives, healthcare devices and high-tech tools,
- Thanks to their efficiency per volume, small magnets offer high magnetic performance, in miniature format,
Disadvantages of magnetic elements:
- They are prone to breaking when subjected to a heavy impact. If the magnets are exposed to shocks, we recommend in a steel housing. The steel housing, in the form of a holder, protects the magnet from cracks and additionally increases its overall durability,
- Magnets lose power when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible power drop (influenced by the magnet’s structure). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
- Due to corrosion risk in humid conditions, it is wise to use sealed magnets made of plastic for outdoor use,
- The use of a protective casing or external holder is recommended, since machining multi-axis shapes in neodymium magnets is risky,
- Possible threat related to magnet particles may arise, when consumed by mistake, which is crucial in the protection of children. It should also be noted that small elements from these devices can disrupt scanning once in the system,
- In cases of mass production, neodymium magnet cost may be a barrier,
Handle Neodymium Magnets with Caution
Neodymium magnets can demagnetize at high temperatures.
While Neodymium magnets can lose their magnetic properties at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.
Neodymium magnets are not recommended for 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.
Magnets are not toys, youngest should not play with them.
Remember that 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.
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.
Neodymium magnets will bounce and also clash together within a radius of several to around 10 cm from each other.
Dust and powder from neodymium magnets are 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.
The magnet coating contains nickel, so be cautious 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.
Avoid bringing neodymium magnets close to a phone or GPS.
Neodymium magnets produce intense magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets are delicate and can easily break and get damaged.
Neodymium magnets are delicate as well as will break if allowed to collide with each other, even from a distance of a few centimeters. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of connection between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
Neodymium magnets are the most powerful magnets ever created, and their strength can surprise you.
To handle magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
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. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.
