Other proposals
Pros as well as cons of Nd2Fe14B magnets.
Advantages
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- Magnets very well resist against loss of magnetization caused by foreign field sources,
- Thanks to the elegant finish, the surface of Ni-Cu-Ni, gold-plated, or silver gives an modern appearance,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures approaching 230°C and above...
- Thanks to freedom in forming and the ability to adapt to client solutions,
- Key role in electronics industry – they serve a role in HDD drives, drive modules, precision medical tools, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power 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 protects the magnet and simultaneously improves its 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
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited possibility of making threads in the magnet and complex shapes - recommended is cover - magnetic holder.
- Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Furthermore, tiny parts of these magnets can be problematic in diagnostics medical in case of swallowing.
- Due to complex production process, their price is higher than average,
Lifting parameters
Maximum magnetic pulling force – what it depends on?
- with the use of a sheet made of low-carbon steel, ensuring full magnetic saturation
- possessing a thickness of minimum 10 mm to ensure full flux closure
- characterized by even structure
- with direct contact (no paint)
- for force applied at a right angle (pull-off, not shear)
- at standard ambient temperature
Lifting capacity in practice – influencing factors
- Distance – existence of any layer (paint, tape, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Plate thickness – too thin plate does not close the flux, causing part of the flux to be wasted to the other side.
- Material composition – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
- Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet and the plate reduces the load capacity.
Safe handling of neodymium magnets
Mechanical processing
Machining of neodymium magnets carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Safe operation
Handle with care. Rare earth magnets attract from a distance and snap with massive power, often quicker than you can move away.
Maximum temperature
Regular neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Electronic hazard
Very strong magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Stay away of min. 10 cm.
Finger safety
Big blocks can crush fingers in a fraction of a second. Do not put your hand betwixt two strong magnets.
Avoid contact if allergic
It is widely known that the nickel plating (the usual finish) is a strong allergen. For allergy sufferers, prevent direct skin contact or choose coated magnets.
Compass and GPS
Remember: neodymium magnets generate a field that disrupts precision electronics. Maintain a separation from your mobile, device, and GPS.
Swallowing risk
Always keep magnets away from children. Choking hazard is high, and the consequences of magnets connecting inside the body are life-threatening.
Beware of splinters
Beware of splinters. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Wear goggles.
Medical implants
For implant holders: Powerful magnets affect electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.
