Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to their tremendous strength, neodymium magnets offer the following advantages:
- Their strength is maintained, and after around ten years, it drops only by ~1% (according to research),
- They show strong resistance to demagnetization from outside magnetic sources,
- Because of the lustrous layer of silver, the component looks aesthetically refined,
- They exhibit superior levels of magnetic induction near the outer area of the magnet,
- These magnets tolerate extreme temperatures, often exceeding 230°C, when properly designed (in relation to form),
- The ability for custom shaping and customization to individual needs – neodymium magnets can be manufactured in many forms and dimensions, which enhances their versatility in applications,
- Key role in new technology industries – they are utilized in hard drives, electric motors, healthcare devices as well as technologically developed systems,
- Relatively small size with high magnetic force – neodymium magnets offer intense magnetic field in tiny dimensions, which makes them useful in small systems
Disadvantages of NdFeB magnets:
- They can break when subjected to a powerful impact. If the magnets are exposed to physical collisions, it is advisable to use in a metal holder. The steel housing, in the form of a holder, protects the magnet from breakage and enhances its overall robustness,
- Magnets lose pulling force when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible magnetic decay (influenced by the magnet’s dimensions). 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,
- Limited ability to create precision features in the magnet – the use of a magnetic holder is recommended,
- Potential hazard linked to microscopic shards may arise, in case of ingestion, which is crucial in the context of child safety. Furthermore, minuscule fragments from these products might interfere with diagnostics if inside the body,
- Higher purchase price is one of the drawbacks compared to ceramic magnets, especially in budget-sensitive applications
Detachment force of the magnet in optimal conditions – what affects it?
The given lifting capacity of the magnet means the maximum lifting force, calculated in ideal conditions, that is:
- with mild steel, serving as a magnetic flux conductor
- with a thickness of minimum 10 mm
- with a polished side
- in conditions of no clearance
- with vertical force applied
- under standard ambient temperature
Practical lifting capacity: influencing factors
In practice, the holding capacity of a magnet is affected by these factors, in descending order of importance:
- Air gap between the magnet and the plate, since even a very small distance (e.g. 0.5 mm) can cause 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 testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance {between} the magnet and the plate lowers the load capacity.
Caution with Neodymium Magnets
Never bring neodymium magnets close to a phone and GPS.
Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS 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.
People with pacemakers are advised to avoid neodymium magnets.
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.
Dust and powder from neodymium magnets are highly flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their strength can surprise you.
Familiarize yourself with our information to correctly handle these magnets and avoid significant injuries to your body and prevent disruption to the magnets.
Keep neodymium magnets away from the wallet, computer, and TV.
Neodymium magnets generate strong magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also destroy devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Neodymium magnetic are known for their fragility, which can cause them to shatter.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.
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 case of placing a finger in the path of a neodymium magnet, in that situation, a cut or even a fracture may occur.
Avoid contact with neodymium magnets 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.
Magnets should not be treated as toys. Therefore, it is not recommended for children to have access to 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.
