Strengths as well as weaknesses of rare earth magnets.
Strengths
- They have unchanged lifting capacity, and over more than ten years their attraction force decreases symbolically – ~1% (according to theory),
- Magnets very well resist against demagnetization caused by ambient magnetic noise,
- Thanks to the smooth finish, the coating of nickel, gold, or silver gives an modern appearance,
- The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the possibility of accurate forming and customization to specialized requirements, neodymium magnets can be modeled in a broad palette of geometric configurations, which makes them more universal,
- Universal use in high-tech industry – they serve a role in mass storage devices, motor assemblies, diagnostic systems, also industrial machines.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a strong case, which not only secures them against impacts but also raises 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 and 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 start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- We suggest casing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complex forms.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. Furthermore, small elements of these products are able to disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Magnetic strength at its maximum – what contributes to it?
- with the application of a sheet made of low-carbon steel, ensuring full magnetic saturation
- with a cross-section of at least 10 mm
- characterized by lack of roughness
- without the slightest air gap between the magnet and steel
- during detachment in a direction perpendicular to the mounting surface
- at standard ambient temperature
Key elements affecting lifting force
- Distance (betwixt the magnet and the metal), since even a microscopic distance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of nominal force).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Plate material – low-carbon steel gives the best results. Higher carbon content decrease magnetic permeability and holding force.
- Smoothness – full contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
- Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was determined by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Data carriers
Powerful magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Stay away of at least 10 cm.
Medical implants
Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Flammability
Fire hazard: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.
Safe operation
Use magnets consciously. Their huge power can shock even experienced users. Stay alert and respect their power.
Do not overheat magnets
Avoid heat. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Physical harm
Big blocks can smash fingers in a fraction of a second. Never place your hand between two strong magnets.
Material brittleness
Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Threat to navigation
GPS units and mobile phones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Adults only
Only for adults. Tiny parts pose a choking risk, leading to intestinal necrosis. Keep away from kids and pets.
Avoid contact if allergic
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction occurs, immediately stop handling magnets and wear gloves.
