Advantages as well as disadvantages of Nd2Fe14B magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- They retain their magnetic properties even under external field action,
- In other words, due to the shiny surface of gold, the element becomes visually attractive,
- They show high magnetic induction at the operating surface, which increases their power,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to freedom in shaping and the capacity to adapt to specific needs,
- Huge importance in modern technologies – they serve a role in mass storage devices, electric motors, advanced medical instruments, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in miniature devices
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- Neodymium magnets lose their strength 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 durability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Limited ability of producing threads in the magnet and complicated shapes - recommended is a housing - mounting mechanism.
- Potential hazard related to microscopic parts 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 complicate diagnosis medical after entering the body.
- Due to neodymium price, their price is higher than average,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what affects it?
- on a base made of mild steel, optimally conducting the magnetic field
- with a thickness no less than 10 mm
- characterized by smoothness
- with direct contact (no impurities)
- for force acting at a right angle (in the magnet axis)
- in stable room temperature
What influences lifting capacity in practice
- Space between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Plate thickness – too thin steel causes magnetic saturation, causing part of the power to be escaped into the air.
- Steel grade – the best choice is high-permeability steel. Cast iron may attract less.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate reduces the lifting capacity.
Safety rules for work with neodymium magnets
Danger to pacemakers
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Electronic devices
Do not bring magnets near a wallet, laptop, or TV. The magnetism can destroy these devices and wipe information from cards.
Material brittleness
NdFeB magnets are ceramic materials, which means they are very brittle. Impact of two magnets will cause them breaking into shards.
Bodily injuries
Big blocks can smash fingers instantly. Under no circumstances place your hand betwixt two attracting surfaces.
Immense force
Handle magnets consciously. Their immense force can surprise even experienced users. Be vigilant and respect their force.
Swallowing risk
Neodymium magnets are not suitable for play. Eating a few magnets can lead to them pinching intestinal walls, which constitutes a direct threat to life and requires immediate surgery.
Compass and GPS
Navigation devices and smartphones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.
Nickel allergy
Some people have a sensitization to nickel, which is the standard coating for NdFeB magnets. Extended handling might lead to dermatitis. It is best to wear protective gloves.
Permanent damage
Watch the temperature. Heating the magnet to high heat will permanently weaken its magnetic structure and pulling force.
Machining danger
Drilling and cutting of NdFeB material carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
