Pros and cons of Nd2Fe14B magnets.
Benefits
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
- Magnets perfectly resist against loss of magnetization caused by ambient magnetic noise,
- By applying a smooth coating of gold, the element gains an modern look,
- Magnets have excellent magnetic induction on the active area,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of custom shaping as well as adjusting to concrete conditions,
- Fundamental importance in electronics industry – they find application in hard drives, brushless drives, advanced medical instruments, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in compact constructions
Cons
- At very strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Limited possibility of making threads in the magnet and complicated shapes - recommended is cover - magnetic holder.
- Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that small components of these devices are able to complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Magnetic strength at its maximum – what affects it?
- on a base made of mild steel, optimally conducting the magnetic field
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with an ground contact surface
- with total lack of distance (no paint)
- under axial force vector (90-degree angle)
- in neutral thermal conditions
Impact of factors on magnetic holding capacity in practice
- Distance (betwixt the magnet and the plate), since even a very small distance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, rust or debris).
- Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Base massiveness – too thin sheet does not accept the full field, causing part of the flux to be lost to the other side.
- Steel grade – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
- Smoothness – full contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Temperature influence – hot environment weakens pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
Warnings
Allergy Warning
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, cease working with magnets and wear gloves.
Phone sensors
Navigation devices and smartphones are highly sensitive to magnetic fields. Direct contact with a strong magnet can ruin the internal compass in your phone.
Heat warning
Standard neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.
Crushing risk
Risk of injury: The attraction force is so immense that it can result in blood blisters, pinching, and broken bones. Use thick gloves.
Protective goggles
Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Swallowing risk
Only for adults. Tiny parts pose a choking risk, causing severe trauma. Keep away from kids and pets.
Danger to pacemakers
Warning for patients: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or request help to work with the magnets.
Mechanical processing
Combustion risk: Rare earth powder is explosive. Do not process magnets in home conditions as this may cause fire.
Safe distance
Data protection: Neodymium magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).
Caution required
Exercise caution. Neodymium magnets act from a distance and snap with huge force, often quicker than you can move away.
