Pros and cons of Nd2Fe14B magnets.
Advantages
- They retain full power for around ten years – the loss is just ~1% (in theory),
- Magnets perfectly defend themselves against loss of magnetization caused by ambient magnetic noise,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Magnets have exceptionally strong magnetic induction on the surface,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Considering the possibility of free shaping and adaptation to individualized needs, magnetic components can be modeled in a variety of geometric configurations, which amplifies use scope,
- Key role in innovative solutions – they find application in hard drives, drive modules, precision medical tools, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in compact constructions
Disadvantages
- At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's 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 and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Limited ability of producing threads in the magnet and complex shapes - preferred is casing - mounting mechanism.
- Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that small components of these magnets are able to disrupt the diagnostic process 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
Lifting parameters
Maximum magnetic pulling force – what affects it?
- on a plate made of structural steel, optimally conducting the magnetic flux
- possessing a thickness of at least 10 mm to ensure full flux closure
- with an ideally smooth contact surface
- with total lack of distance (without coatings)
- for force applied at a right angle (pull-off, not shear)
- at conditions approx. 20°C
Magnet lifting force in use – key factors
- Distance – the presence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Chemical composition of the base – mild steel attracts best. Alloy steels reduce magnetic permeability and holding force.
- Surface finish – ideal contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet and the plate reduces the holding force.
Safety rules for work with NdFeB magnets
Finger safety
Watch your fingers. Two large magnets will join immediately with a force of massive weight, crushing everything in their path. Exercise extreme caution!
Fire warning
Mechanical processing of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Medical interference
Health Alert: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Operating temperature
Avoid heat. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Magnetic media
Do not bring magnets close to a wallet, laptop, or TV. The magnetism can permanently damage these devices and erase data from cards.
Swallowing risk
Always store magnets out of reach of children. Choking hazard is significant, and the effects of magnets connecting inside the body are fatal.
Conscious usage
Before use, read the rules. Sudden snapping can break the magnet or injure your hand. Be predictive.
Beware of splinters
Despite the nickel coating, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.
Metal Allergy
It is widely known that nickel (standard magnet coating) is a strong allergen. For allergy sufferers, avoid touching magnets with bare hands or choose encased magnets.
GPS Danger
GPS units and smartphones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
