Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- They have constant strength, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
- They retain their magnetic properties even under external field action,
- In other words, due to the reflective finish of silver, the element gains visual value,
- The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
- 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...
- Possibility of custom machining and adapting to defined conditions,
- Key role in future technologies – they find application in computer drives, electric drive systems, precision medical tools, and modern systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a steel housing, which not only protects them against impacts but also raises their 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 stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing threads and complex forms in magnets, we recommend using cover - magnetic holder.
- Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, small elements of these devices are able to be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum lifting force for a neodymium magnet – what it depends on?
- with the application of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- possessing a massiveness of min. 10 mm to avoid saturation
- with an ground touching surface
- under conditions of gap-free contact (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- at conditions approx. 20°C
Determinants of lifting force in real conditions
- Distance – the presence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
- Steel thickness – too thin plate does not accept the full field, causing part of the power to be lost into the air.
- Material composition – different alloys attracts identically. High carbon content worsen the attraction effect.
- Surface finish – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet and the plate decreases the holding force.
Safety rules for work with neodymium magnets
Avoid contact if allergic
Medical facts indicate that nickel (standard magnet coating) is a common allergen. If you have an allergy, prevent direct skin contact or select coated magnets.
Magnetic interference
Remember: neodymium magnets produce a field that disrupts precision electronics. Maintain a separation from your mobile, device, and GPS.
ICD Warning
For implant holders: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or request help to handle the magnets.
Risk of cracking
Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets will cause them cracking into small pieces.
Cards and drives
Powerful magnetic fields can erase data on credit cards, hard drives, and storage devices. Stay away of min. 10 cm.
Fire warning
Combustion risk: Neodymium dust is explosive. Do not process magnets in home conditions as this may cause fire.
Crushing risk
Risk of injury: The pulling power is so immense that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Do not underestimate power
Use magnets with awareness. Their immense force can surprise even experienced users. Plan your moves and respect their power.
Do not give to children
Neodymium magnets are not intended for children. Eating multiple magnets may result in them connecting inside the digestive tract, which poses a critical condition and necessitates urgent medical intervention.
Do not overheat magnets
Standard neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. Damage is permanent.
