Pros as well as cons of rare earth magnets.
Advantages
- They have stable power, and over nearly ten years their performance decreases symbolically – ~1% (in testing),
- They do not lose their magnetic properties even under external field action,
- A magnet with a shiny gold surface is more attractive,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
- Possibility of custom modeling and adapting to individual conditions,
- Huge importance in future technologies – they serve a role in mass storage devices, motor assemblies, advanced medical instruments, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in miniature devices
Limitations
- Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only secures them against impacts but also increases their 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 very resistant to heat
- 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 secure oxidation as well as corrosion.
- Limited possibility of producing nuts in the magnet and complicated shapes - recommended is casing - magnet mounting.
- Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the context of child safety. Furthermore, small elements of these devices can disrupt the diagnostic process medical after entering the body.
- Due to expensive raw materials, their price is higher than average,
Holding force characteristics
Maximum lifting capacity of the magnet – what it depends on?
- on a base made of structural steel, perfectly concentrating the magnetic flux
- whose thickness is min. 10 mm
- with a plane perfectly flat
- without any air gap between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at ambient temperature room level
Determinants of lifting force in real conditions
- Clearance – the presence of any layer (rust, dirt, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is high-permeability steel. Cast iron may generate lower lifting capacity.
- Surface structure – the more even the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate decreases the holding force.
Precautions when working with NdFeB magnets
Handling guide
Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
Fire warning
Combustion risk: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.
Sensitization to coating
Some people have a contact allergy to Ni, which is the common plating for NdFeB magnets. Frequent touching might lead to dermatitis. We suggest wear safety gloves.
Life threat
Individuals with a ICD have to maintain an large gap from magnets. The magnetism can interfere with the operation of the implant.
Danger to the youngest
Absolutely keep magnets out of reach of children. Choking hazard is significant, and the effects of magnets clamping inside the body are life-threatening.
Do not overheat magnets
Avoid heat. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Compass and GPS
An intense magnetic field negatively affects the functioning of compasses in smartphones and navigation systems. Keep magnets close to a device to avoid breaking the sensors.
Electronic devices
Avoid bringing magnets close to a wallet, laptop, or screen. The magnetism can permanently damage these devices and erase data from cards.
Physical harm
Big blocks can smash fingers instantly. Under no circumstances place your hand betwixt two strong magnets.
Shattering risk
NdFeB magnets are sintered ceramics, which means they are fragile like glass. Impact of two magnets will cause them shattering into small pieces.
