Strengths and weaknesses of Nd2Fe14B magnets.
Strengths
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (based on calculations),
- Magnets effectively resist against loss of magnetization caused by foreign field sources,
- In other words, due to the glossy finish of silver, the element looks attractive,
- They show high magnetic induction at the operating surface, which increases their power,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of accurate creating and adapting to individual applications,
- Wide application in modern industrial fields – they serve a role in data components, motor assemblies, medical devices, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in small systems
Limitations
- At very strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- We suggest casing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complicated shapes.
- Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. It is also worth noting that small elements of these devices are able to complicate diagnosis medical when they are in the body.
- With large orders the cost of neodymium magnets can be a barrier,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what it depends on?
- on a plate made of structural steel, optimally conducting the magnetic field
- possessing a massiveness of min. 10 mm to avoid saturation
- characterized by smoothness
- without any insulating layer between the magnet and steel
- under vertical application of breakaway force (90-degree angle)
- in temp. approx. 20°C
Practical lifting capacity: influencing factors
- Distance (between the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
- Material type – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
- Surface structure – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
- Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was measured using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
Precautions when working with NdFeB magnets
Thermal limits
Monitor thermal conditions. Heating the magnet to high heat will destroy its properties and pulling force.
Hand protection
Risk of injury: The attraction force is so great that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Fire risk
Dust created during grinding of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Precision electronics
Remember: neodymium magnets generate a field that disrupts sensitive sensors. Keep a safe distance from your mobile, tablet, and navigation systems.
Life threat
For implant holders: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or request help to handle the magnets.
Material brittleness
Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.
Electronic devices
Intense magnetic fields can erase data on payment cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.
Allergic reactions
It is widely known that nickel (the usual finish) is a potent allergen. For allergy sufferers, avoid touching magnets with bare hands and opt for encased magnets.
Swallowing risk
Absolutely keep magnets away from children. Choking hazard is significant, and the effects of magnets clamping inside the body are tragic.
Handling rules
Handle with care. Neodymium magnets attract from a distance and snap with massive power, often faster than you can move away.
