Pros as well as cons of neodymium magnets.
Advantages
- They do not lose strength, even after around ten years – the drop in lifting capacity is only ~1% (based on measurements),
- They are noted for resistance to demagnetization induced by external disturbances,
- By using a reflective layer of nickel, the element gains an nice look,
- Magnetic induction on the working layer of the magnet remains strong,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
- Possibility of custom forming and optimizing to defined needs,
- Versatile presence in high-tech industry – they are used in HDD drives, electric drive systems, advanced medical instruments, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in compact constructions
Weaknesses
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets decrease their power 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
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing nuts and complex shapes in magnets, we propose using a housing - magnetic mount.
- Potential hazard related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. It is also worth noting that tiny parts of these products are able to complicate diagnosis medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what affects it?
- with the application of a sheet made of special test steel, guaranteeing maximum field concentration
- possessing a massiveness of minimum 10 mm to avoid saturation
- characterized by smoothness
- with direct contact (without impurities)
- under axial application of breakaway force (90-degree angle)
- in neutral thermal conditions
Magnet lifting force in use – key factors
- Gap (betwixt the magnet and the metal), because even a very small distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Load vector – maximum parameter is reached only during pulling at a 90° angle. The shear force of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – too thin sheet causes magnetic saturation, causing part of the power to be wasted into the air.
- Chemical composition of the base – mild steel attracts best. Alloy steels lower magnetic properties and holding force.
- Surface finish – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, however under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet and the plate lowers the holding force.
Warnings
Respect the power
Handle magnets with awareness. Their powerful strength can shock even professionals. Be vigilant and do not underestimate their power.
Serious injuries
Mind your fingers. Two large magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Avoid contact if allergic
Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. For allergy sufferers, avoid touching magnets with bare hands and choose versions in plastic housing.
Life threat
People with a ICD must keep an safe separation from magnets. The magnetic field can stop the operation of the implant.
This is not a toy
These products are not suitable for play. Swallowing multiple magnets may result in them pinching intestinal walls, which poses a critical condition and requires urgent medical intervention.
Shattering risk
Neodymium magnets are sintered ceramics, meaning they are very brittle. Clashing of two magnets will cause them shattering into shards.
GPS Danger
A powerful magnetic field negatively affects the functioning of magnetometers in smartphones and navigation systems. Do not bring magnets close to a device to avoid damaging the sensors.
Heat warning
Do not overheat. Neodymium magnets are susceptible to heat. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
Threat to electronics
Powerful magnetic fields can destroy records on credit cards, hard drives, and storage devices. Maintain a gap of min. 10 cm.
Fire risk
Machining of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
