Pros as well as cons of Nd2Fe14B magnets.
Pros
- Their magnetic field remains stable, and after around 10 years it drops only by ~1% (theoretically),
- Magnets very well protect themselves against loss of magnetization caused by foreign field sources,
- In other words, due to the reflective finish of gold, the element looks attractive,
- Neodymium magnets generate maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to versatility in forming and the capacity to adapt to complex applications,
- Significant place in advanced technology sectors – they serve a role in magnetic memories, brushless drives, diagnostic systems, also complex engineering applications.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Limitations
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated shapes.
- Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these magnets are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Highest magnetic holding force – what affects it?
- on a block made of mild steel, optimally conducting the magnetic field
- whose thickness is min. 10 mm
- with an polished touching surface
- under conditions of gap-free contact (metal-to-metal)
- under vertical force vector (90-degree angle)
- in stable room temperature
Impact of factors on magnetic holding capacity in practice
- Air gap (between the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, corrosion or debris).
- Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of maximum force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Material composition – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
- Surface finish – ideal contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Choking Hazard
Absolutely keep magnets out of reach of children. Choking hazard is high, and the effects of magnets clamping inside the body are very dangerous.
Material brittleness
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Crushing risk
Pinching hazard: The pulling power is so great that it can cause hematomas, crushing, and broken bones. Use thick gloves.
Do not underestimate power
Handle magnets consciously. Their powerful strength can surprise even experienced users. Be vigilant and do not underestimate their power.
Cards and drives
Intense magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Stay away of min. 10 cm.
Allergy Warning
Certain individuals experience a contact allergy to nickel, which is the standard coating for neodymium magnets. Frequent touching may cause an allergic reaction. We recommend wear protective gloves.
Heat warning
Avoid heat. NdFeB magnets are sensitive to temperature. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Dust explosion hazard
Fire warning: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Medical implants
People with a ICD must maintain an safe separation from magnets. The magnetic field can interfere with the operation of the life-saving device.
GPS and phone interference
Remember: neodymium magnets produce a field that interferes with precision electronics. Maintain a safe distance from your phone, device, and GPS.
