Pros and cons of Nd2Fe14B magnets.
Strengths
- Their strength is maintained, and after around ten years it decreases only by ~1% (theoretically),
- Neodymium magnets prove to be extremely resistant to demagnetization caused by external field sources,
- In other words, due to the metallic surface of nickel, the element looks attractive,
- They feature high magnetic induction at the operating surface, which increases their power,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the possibility of accurate forming and adaptation to custom needs, magnetic components can be produced in a wide range of geometric configurations, which makes them more universal,
- Significant place in electronics industry – they serve a role in mass storage devices, electromotive mechanisms, medical equipment, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in compact constructions
Limitations
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend a housing - magnetic mount, due to difficulties in producing threads inside the magnet and complicated forms.
- Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Furthermore, small components of these devices can complicate diagnosis medical when they are in the body.
- Due to complex production process, their price is relatively high,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what affects it?
- with the contact of a yoke made of special test steel, ensuring maximum field concentration
- with a cross-section no less than 10 mm
- with a plane free of scratches
- under conditions of no distance (surface-to-surface)
- under perpendicular application of breakaway force (90-degree angle)
- in neutral thermal conditions
Impact of factors on magnetic holding capacity in practice
- Distance (between the magnet and the metal), as even a tiny clearance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Base massiveness – too thin sheet does not accept the full field, causing part of the power to be escaped into the air.
- Metal type – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
- Surface quality – the more even the plate, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Thermal environment – temperature increase causes a temporary drop of force. Check the maximum operating temperature for a given model.
Lifting capacity was measured by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, however under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Safe handling of NdFeB magnets
Shattering risk
Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
No play value
Always keep magnets away from children. Choking hazard is high, and the effects of magnets connecting inside the body are very dangerous.
Handling rules
Use magnets with awareness. Their powerful strength can shock even experienced users. Be vigilant and do not underestimate their power.
Physical harm
Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, crushing everything in their path. Exercise extreme caution!
Nickel coating and allergies
Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, prevent touching magnets with bare hands or choose versions in plastic housing.
Medical implants
Warning for patients: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.
Phone sensors
Navigation devices and smartphones are highly sensitive to magnetism. Close proximity with a strong magnet can ruin the sensors in your phone.
Power loss in heat
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its properties and pulling force.
Protect data
Avoid bringing magnets near a purse, computer, or screen. The magnetic field can destroy these devices and erase data from cards.
Dust is flammable
Powder created during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
