Pros as well as cons of Nd2Fe14B magnets.
Strengths
- They retain full power for nearly 10 years – the loss is just ~1% (in theory),
- They do not lose their magnetic properties even under strong external field,
- A magnet with a shiny silver surface has an effective appearance,
- The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to versatility in shaping and the capacity to adapt to individual projects,
- Key role in future technologies – they serve a role in mass storage devices, drive modules, medical equipment, and modern systems.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
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 demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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 extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- We suggest a housing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated shapes.
- Possible danger to health – tiny shards 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 small elements of these devices can complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum lifting force for a neodymium magnet – what contributes to it?
- with the contact of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- whose thickness equals approx. 10 mm
- with a surface perfectly flat
- under conditions of gap-free contact (surface-to-surface)
- for force applied at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Air gap (between the magnet and the plate), because even a microscopic clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Load vector – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Material type – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
- Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Temperature – heating the magnet results in weakening of induction. Check the thermal limit for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the load capacity is reduced by as much as 75%. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
Safe handling of neodymium magnets
Choking Hazard
Product intended for adults. Tiny parts pose a choking risk, causing serious injuries. Keep out of reach of children and animals.
Physical harm
Mind your fingers. Two powerful magnets will join immediately with a force of massive weight, destroying everything in their path. Be careful!
Permanent damage
Avoid heat. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).
Dust explosion hazard
Combustion risk: Neodymium dust is highly flammable. Do not process magnets without safety gear as this risks ignition.
Caution required
Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Sensitization to coating
Medical facts indicate that the nickel plating (the usual finish) is a strong allergen. If you have an allergy, prevent direct skin contact or choose versions in plastic housing.
Magnet fragility
NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets will cause them cracking into shards.
Precision electronics
An intense magnetic field disrupts the functioning of magnetometers in smartphones and GPS navigation. Maintain magnets close to a device to avoid damaging the sensors.
Warning for heart patients
Warning for patients: Strong magnetic fields affect electronics. Keep at least 30 cm distance or request help to work with the magnets.
Electronic devices
Intense magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
