Pros and cons of neodymium magnets.
Pros
- They do not lose power, even over approximately 10 years – the decrease in strength is only ~1% (theoretically),
- They do not lose their magnetic properties even under strong external field,
- In other words, due to the smooth layer of nickel, the element looks attractive,
- Magnetic induction on the working part of the magnet is impressive,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to versatility in shaping and the capacity to modify to specific needs,
- Significant place in advanced technology sectors – they are used in magnetic memories, electric motors, medical equipment, as well as modern systems.
- 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 housings. Such a solution protects the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest 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 resistant to moisture, in case of application outdoors
- Due to limitations in producing threads and complex forms in magnets, we propose using casing - magnetic holder.
- Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these devices are able to be problematic in diagnostics medical when they are in the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Pull force analysis
Maximum lifting force for a neodymium magnet – what contributes to it?
- on a block made of structural steel, effectively closing the magnetic field
- with a cross-section of at least 10 mm
- characterized by smoothness
- under conditions of no distance (metal-to-metal)
- under axial force vector (90-degree angle)
- at temperature room level
Lifting capacity in practice – influencing factors
- Gap (betwixt the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
- Angle of force application – highest force is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Steel thickness – too thin steel does not close the flux, causing part of the power to be lost into the air.
- Metal type – not every steel attracts identically. Alloy additives worsen the attraction effect.
- Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet and the plate lowers the lifting capacity.
Safety rules for work with neodymium magnets
Allergy Warning
Nickel alert: The nickel-copper-nickel coating contains nickel. If skin irritation occurs, cease handling magnets and wear gloves.
Danger to the youngest
These products are not suitable for play. Swallowing several magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and necessitates urgent medical intervention.
Machining danger
Powder created during machining of magnets is combustible. Do not drill into magnets unless you are an expert.
Magnetic interference
Be aware: rare earth magnets produce a field that disrupts sensitive sensors. Maintain a safe distance from your mobile, tablet, and GPS.
Magnets are brittle
Protect your eyes. Magnets can fracture upon violent connection, launching shards into the air. Wear goggles.
Crushing force
Danger of trauma: The attraction force is so immense that it can result in hematomas, crushing, and broken bones. Protective gloves are recommended.
Life threat
Warning for patients: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or ask another person to handle the magnets.
Immense force
Handle magnets consciously. Their powerful strength can surprise even professionals. Stay alert and respect their power.
Operating temperature
Keep cool. NdFeB magnets are sensitive to temperature. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
Magnetic media
Powerful magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
