Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to their magnetic efficiency, neodymium magnets provide the following advantages:
- They do not lose their power around ten years – the loss of strength is only ~1% (theoretically),
- They are extremely resistant to demagnetization caused by external magnetic sources,
- By applying a shiny layer of gold, the element gains a modern look,
- They have exceptional magnetic induction on the surface of the magnet,
- They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
- The ability for accurate shaping and customization to custom needs – neodymium magnets can be manufactured in many forms and dimensions, which enhances their versatility in applications,
- Key role in modern technologies – they serve a purpose in computer drives, electric motors, healthcare devices or even technologically developed systems,
- Relatively small size with high magnetic force – neodymium magnets offer intense magnetic field in compact dimensions, which makes them ideal in miniature devices
Disadvantages of NdFeB magnets:
- They are prone to breaking when subjected to a strong impact. If the magnets are exposed to physical collisions, they should be placed in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from damage and enhances its overall strength,
- Magnets lose power when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible magnetic decay (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 rubber for outdoor use,
- Limited ability to create precision features in the magnet – the use of a housing is recommended,
- Possible threat due to small fragments may arise, especially if swallowed, which is significant in the family environments. Furthermore, tiny components from these assemblies might hinder health screening after being swallowed,
- High unit cost – neodymium magnets are costlier than other types of magnets (e.g., ferrite), which can restrict large-scale applications
Handle Neodymium Magnets Carefully
Do not place neodymium magnets near a computer HDD, TV, and wallet.
Strong magnetic fields emitted by neodymium magnets can destroy magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
Neodymium magnets will bounce and also contact together within a radius of several to around 10 cm from each other.
Keep neodymium magnets away from GPS and smartphones.
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.
People with pacemakers are advised to avoid neodymium magnets.
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.
The magnet is coated with nickel - be careful 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.
Neodymium magnets can demagnetize at high temperatures.
Despite the fact that magnets have been observed to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Neodymium magnets are characterized by being fragile, which can cause them to become damaged.
Neodymium magnetic are fragile and 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 strongest magnets ever created, and their strength can shock you.

It is important to keep neodymium magnets away from children.
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.
