Other offers
Advantages as well as disadvantages of Nd2Fe14B magnets.
Benefits
- Their power remains stable, and after around ten years it drops only by ~1% (theoretically),
- Neodymium magnets are characterized by extremely resistant to magnetic field loss caused by external field sources,
- Thanks to the elegant finish, the surface of nickel, gold-plated, or silver gives an aesthetic appearance,
- They are known for high magnetic induction at the operating surface, which improves attraction properties,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
- Thanks to modularity in constructing and the capacity to customize to unusual requirements,
- Key role in modern technologies – they serve a role in hard drives, motor assemblies, medical devices, as well as other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We suggest cover - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complex shapes.
- Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements of these magnets can disrupt the diagnostic process medical after entering the body.
- With mass production the cost of neodymium magnets is economically unviable,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what it depends on?
- on a plate made of mild steel, optimally conducting the magnetic flux
- with a thickness of at least 10 mm
- with an polished touching surface
- under conditions of gap-free contact (metal-to-metal)
- under vertical application of breakaway force (90-degree angle)
- at temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Space between surfaces – every millimeter of separation (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Load vector – maximum parameter is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Steel grade – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
- Surface condition – ground elements ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and in frost 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. Additionally, even a small distance between the magnet’s surface and the plate lowers the holding force.
H&S for magnets
Electronic devices
Do not bring magnets close to a purse, laptop, or screen. The magnetism can destroy these devices and wipe information from cards.
Do not overheat magnets
Do not overheat. NdFeB magnets are sensitive to heat. If you require operation above 80°C, inquire about HT versions (H, SH, UH).
Hand protection
Watch your fingers. Two large magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!
Swallowing risk
Product intended for adults. Small elements pose a choking risk, causing intestinal necrosis. Keep out of reach of kids and pets.
Magnets are brittle
NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Clashing of two magnets will cause them shattering into shards.
Immense force
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
Threat to navigation
Remember: rare earth magnets produce a field that disrupts precision electronics. Keep a separation from your mobile, device, and GPS.
Fire warning
Drilling and cutting of neodymium magnets poses a fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Avoid contact if allergic
Studies show that nickel (standard magnet coating) is a potent allergen. If you have an allergy, avoid touching magnets with bare hands or opt for coated magnets.
Medical implants
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
