Advantages as well as disadvantages of Nd2Fe14B magnets.
Benefits
- Their power is maintained, and after approximately 10 years it drops only by ~1% (theoretically),
- Magnets perfectly protect themselves against demagnetization caused by external fields,
- Thanks to the shimmering finish, the surface of Ni-Cu-Ni, gold, or silver gives an professional appearance,
- Magnetic induction on the working layer of the magnet is impressive,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to the possibility of flexible forming and customization to individualized requirements, magnetic components can be created in a wide range of geometric configurations, which makes them more universal,
- Universal use in innovative solutions – they are commonly used in HDD drives, electric drive systems, medical devices, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in small systems
Limitations
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We suggest a housing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated shapes.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these magnets can be problematic in diagnostics medical in case of swallowing.
- Due to expensive raw materials, their price is higher than average,
Lifting parameters
Maximum magnetic pulling force – what affects it?
- using a sheet made of low-carbon steel, acting as a ideal flux conductor
- with a thickness minimum 10 mm
- characterized by smoothness
- under conditions of gap-free contact (surface-to-surface)
- during pulling in a direction perpendicular to the mounting surface
- at room temperature
Practical lifting capacity: influencing factors
- Gap between magnet and steel – every millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Load vector – highest force is available only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Steel thickness – too thin plate does not accept the full field, causing part of the flux to be lost to the other side.
- Steel grade – ideal substrate is pure iron steel. Hardened steels may have worse magnetic properties.
- Surface quality – the more even the surface, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Thermal environment – temperature increase causes a temporary drop of force. Check the thermal limit for a given model.
Lifting capacity was assessed using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate decreases the lifting capacity.
Precautions when working with neodymium magnets
Maximum temperature
Regular neodymium magnets (grade N) lose power when the temperature goes above 80°C. This process is irreversible.
Do not give to children
Only for adults. Small elements pose a choking risk, causing serious injuries. Store out of reach of children and animals.
Nickel allergy
Certain individuals have a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Frequent touching may cause skin redness. We strongly advise wear protective gloves.
Do not underestimate power
Handle with care. Neodymium magnets attract from a long distance and snap with massive power, often faster than you can move away.
Serious injuries
Watch your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Fire risk
Combustion risk: Neodymium dust is highly flammable. Do not process magnets without safety gear as this may cause fire.
Eye protection
Despite metallic appearance, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Pacemakers
For implant holders: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.
Compass and GPS
Be aware: neodymium magnets generate a field that confuses precision electronics. Keep a safe distance from your mobile, tablet, and navigation systems.
Electronic hazard
Do not bring magnets close to a wallet, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.
