Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- They do not lose power, even over nearly 10 years – the reduction in lifting capacity is only ~1% (theoretically),
- They have excellent resistance to weakening of magnetic properties when exposed to external magnetic sources,
- The use of an refined finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnetic induction on the working part of the magnet remains strong,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to flexibility in shaping and the ability to adapt to client solutions,
- Significant place in future technologies – they serve a role in hard drives, drive modules, medical devices, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in compact constructions
Limitations
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in creating nuts and complex forms in magnets, we recommend using a housing - magnetic mount.
- Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. Additionally, small components of these devices are able to disrupt the diagnostic process medical when they are in the body.
- Due to expensive raw materials, their price exceeds standard values,
Holding force characteristics
Highest magnetic holding force – what affects it?
- on a plate made of mild steel, perfectly concentrating the magnetic field
- whose transverse dimension is min. 10 mm
- with an ideally smooth touching surface
- under conditions of gap-free contact (metal-to-metal)
- under perpendicular application of breakaway force (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Distance – the presence of any layer (paint, dirt, air) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys attracts identically. High carbon content worsen the attraction effect.
- Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Power loss in heat
Avoid heat. NdFeB magnets are susceptible to heat. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
Dust explosion hazard
Machining of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Precision electronics
GPS units and smartphones are extremely susceptible to magnetism. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
Caution required
Use magnets consciously. Their immense force can surprise even experienced users. Be vigilant and respect their force.
Magnet fragility
Watch out for shards. Magnets can explode upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Implant safety
People with a ICD should keep an absolute distance from magnets. The magnetism can interfere with the operation of the implant.
Crushing risk
Mind your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!
Electronic hazard
Do not bring magnets close to a wallet, laptop, or TV. The magnetic field can permanently damage these devices and erase data from cards.
Allergy Warning
Nickel alert: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, cease working with magnets and wear gloves.
Do not give to children
These products are not suitable for play. Swallowing multiple magnets may result in them connecting inside the digestive tract, which poses a critical condition and requires urgent medical intervention.
