Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their long-term stability, neodymium magnets provide the following advantages:
- They do not lose their magnetism, even after approximately 10 years – the loss of strength is only ~1% (theoretically),
- They protect against demagnetization induced by surrounding magnetic fields effectively,
- Because of the reflective layer of nickel, the component looks aesthetically refined,
- They exhibit elevated levels of magnetic induction near the outer area of the magnet,
- They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
- Thanks to the possibility in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in various configurations, which expands their usage potential,
- Important function in modern technologies – they are used in data storage devices, electric drives, healthcare devices or even technologically developed systems,
- Relatively small size with high magnetic force – neodymium magnets offer strong power in small dimensions, which allows for use in miniature devices
Disadvantages of rare earth magnets:
- They can break when subjected to a strong impact. If the magnets are exposed to shocks, it is suggested to place them in a metal holder. The steel housing, in the form of a holder, protects the magnet from cracks and additionally enhances its overall robustness,
- Magnets lose power when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible performance loss (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,
- They rust in a humid environment – during outdoor use, we recommend using moisture-resistant magnets, such as those made of rubber,
- Limited ability to create complex details in the magnet – the use of a mechanical support is recommended,
- Potential hazard from tiny pieces may arise, in case of ingestion, which is notable in the family environments. Furthermore, small elements from these magnets have the potential to complicate medical imaging after being swallowed,
- Due to a complex production process, their cost is considerably higher,
Maximum lifting capacity of the magnet – what affects it?
The given strength of the magnet corresponds to the optimal strength, measured under optimal conditions, that is:
- using a steel plate with low carbon content, acting as a magnetic circuit closure
- having a thickness of no less than 10 millimeters
- with a smooth surface
- in conditions of no clearance
- in a perpendicular direction of force
- under standard ambient temperature
Determinants of lifting force in real conditions
Practical lifting force is dependent on factors, listed from the most critical to the less significant:
- Air gap between the magnet and the plate, since even a very small distance (e.g. 0.5 mm) causes a drop in lifting force of up to 50%.
- Direction of applied force, because the maximum lifting capacity is achieved under perpendicular application. The force required to slide the magnet along the plate is usually several times lower.
- Thickness of the plate, as a plate that is too thin causes part of the magnetic flux not to be used and to remain wasted in the air.
- Material of the plate, because higher carbon content lowers holding force, while higher iron content increases it. The best choice is steel with high magnetic permeability and high saturation induction.
- Surface of the plate, because the more smooth and polished it is, the better the contact and consequently the greater the magnetic saturation.
- Operating temperature, since all permanent magnets have a negative temperature coefficient. This means that at high temperatures they are weaker, while at sub-zero temperatures they become slightly stronger.
* Lifting capacity was assessed with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the holding force is lower. Additionally, even a minimal clearance {between} the magnet’s surface and the plate reduces the holding force.
Caution with Neodymium Magnets
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. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.
You should keep neodymium magnets at a safe distance from the wallet, computer, and TV.
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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
Neodymium magnets can become demagnetized at high temperatures.
Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.
Neodymium magnets are delicate as well as can easily crack as well as get damaged.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. At the moment of collision between the magnets, tiny sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.
Never bring neodymium magnets close to a phone and GPS.
Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.
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.
Neodymium magnets are not recommended for 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.

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.
In the situation of placing a finger in the path of a neodymium magnet, in that situation, a cut or even a fracture may occur.
The magnet coating contains nickel, so be cautious if you have a nickel 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.
