Strengths as well as weaknesses of Nd2Fe14B magnets.
Strengths
- Their power is maintained, and after approximately ten years it drops only by ~1% (theoretically),
- They feature excellent resistance to magnetic field loss when exposed to external fields,
- A magnet with a metallic gold surface is more attractive,
- Magnets are characterized by exceptionally strong magnetic induction on the working surface,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- In view of the option of free forming and customization to unique solutions, magnetic components can be modeled in a variety of forms and dimensions, which expands the range of possible applications,
- Universal use in electronics industry – they serve a role in computer drives, motor assemblies, diagnostic systems, also other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets decrease their force 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. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complicated shapes in magnets, we recommend using cover - magnetic mechanism.
- Possible danger to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. Additionally, small components of these devices can be problematic in diagnostics medical after entering the body.
- Due to neodymium price, their price is relatively high,
Lifting parameters
Maximum lifting capacity of the magnet – what contributes to it?
- with the application of a sheet made of special test steel, guaranteeing full magnetic saturation
- possessing a massiveness of min. 10 mm to avoid saturation
- characterized by lack of roughness
- under conditions of ideal adhesion (surface-to-surface)
- during pulling in a direction perpendicular to the mounting surface
- at temperature room level
Lifting capacity in practice – influencing factors
- Gap between surfaces – every millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Material composition – different alloys attracts identically. Alloy additives weaken the attraction effect.
- Smoothness – full contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was determined using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
Safety rules for work with neodymium magnets
Machining danger
Machining of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Conscious usage
Use magnets consciously. Their immense force can shock even experienced users. Be vigilant and respect their force.
Threat to navigation
Be aware: neodymium magnets generate a field that interferes with precision electronics. Keep a separation from your phone, device, and navigation systems.
Sensitization to coating
Certain individuals have a hypersensitivity to nickel, which is the typical protective layer for neodymium magnets. Extended handling may cause a rash. We strongly advise wear safety gloves.
Medical interference
Patients with a pacemaker must keep an absolute distance from magnets. The magnetism can interfere with the functioning of the implant.
Thermal limits
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
Crushing force
Risk of injury: The pulling power is so great that it can result in blood blisters, pinching, and broken bones. Protective gloves are recommended.
Beware of splinters
NdFeB magnets are ceramic materials, which means they are prone to chipping. Impact of two magnets leads to them breaking into small pieces.
Keep away from computers
Powerful magnetic fields can erase data on credit cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.
Product not for children
Always keep magnets out of reach of children. Choking hazard is high, and the effects of magnets clamping inside the body are very dangerous.
