Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
Besides their high retention, neodymium magnets are valued for these benefits:
- They virtually do not lose power, because even after ten years, the decline in efficiency is only ~1% (according to literature),
- They show strong resistance to demagnetization from external magnetic fields,
- Thanks to the glossy finish and gold coating, they have an elegant appearance,
- The outer field strength of the magnet shows elevated magnetic properties,
- These magnets tolerate high temperatures, often exceeding 230°C, when properly designed (in relation to form),
- With the option for tailored forming and targeted design, these magnets can be produced in various shapes and sizes, greatly improving design adaptation,
- Key role in new technology industries – they find application in data storage devices, electric drives, medical equipment and sophisticated instruments,
- Compactness – despite their small size, they provide high effectiveness, making them ideal for precision applications
Disadvantages of rare earth magnets:
- They are prone to breaking when subjected to a strong impact. If the magnets are exposed to shocks, it is suggested to place them in a protective case. The steel housing, in the form of a holder, protects the magnet from fracture and increases its overall durability,
- Magnets lose power when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible magnetic decay (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 moisture can corrode. Therefore, for outdoor applications, we recommend waterproof types made of coated materials,
- Limited ability to create precision features in the magnet – the use of a magnetic holder is recommended,
- Safety concern due to small fragments may arise, especially if swallowed, which is crucial in the context of child safety. Additionally, tiny components from these magnets might disrupt scanning when ingested,
- Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications
Exercise Caution with Neodymium Magnets
Neodymium Magnets can attract to each other, pinch the skin, and cause significant injuries.
In the situation of holding a finger in the path of a neodymium magnet, in such a case, a cut or a fracture may occur.
Magnets made of neodymium are particularly fragile, resulting in their breakage.
Neodymium magnetic are extremely fragile, and by joining them in an uncontrolled manner, they will break. 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.
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.
Keep neodymium magnets away from GPS and smartphones.
Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.
Neodymium magnets are not recommended for people with pacemakers.
Neodymium magnets generate very strong magnetic fields that can 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.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times stronger, and their strength can shock you.
Familiarize yourself with our information to properly handle these magnets and avoid significant injuries to your body and prevent damage to the magnets.
The magnet coating is made of nickel, so be cautious 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.
Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.
Neodymium magnets produce intense magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.
Magnets should not be treated as toys. Therefore, it is not recommended for children to have access to them.
Neodymium magnets are not toys. You cannot allow them to become toys for children. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
Neodymium magnets can become demagnetized at high temperatures.
Whilst Neodymium magnets can demagnetize 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.
Exercise caution!
