Pros as well as cons of neodymium magnets.
Advantages
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (according to literature),
- They possess excellent resistance to magnetic field loss due to opposing magnetic fields,
- In other words, due to the reflective finish of nickel, the element looks attractive,
- Neodymium magnets ensure maximum magnetic induction on a contact point, which increases force concentration,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of accurate machining as well as optimizing to individual requirements,
- Significant place in modern industrial fields – they are commonly used in magnetic memories, brushless drives, precision medical tools, also other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Limitations
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- We suggest casing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complicated shapes.
- Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these products can disrupt the diagnostic process medical when they are in the body.
- With large orders the cost of neodymium magnets is economically unviable,
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what affects it?
- on a base made of structural steel, effectively closing the magnetic field
- whose transverse dimension is min. 10 mm
- with an polished touching surface
- under conditions of no distance (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- at ambient temperature room level
Lifting capacity in practice – influencing factors
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Material composition – not every steel attracts identically. High carbon content worsen the attraction effect.
- Surface structure – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. 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 optimal thickness, under perpendicular forces, whereas under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet and the plate decreases the lifting capacity.
Warnings
Sensitization to coating
Nickel alert: The nickel-copper-nickel coating consists of nickel. If skin irritation occurs, cease handling magnets and use protective gear.
Eye protection
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
Keep away from electronics
Note: rare earth magnets generate a field that disrupts precision electronics. Keep a separation from your phone, device, and GPS.
Respect the power
Exercise caution. Neodymium magnets act from a long distance and snap with huge force, often faster than you can move away.
Health Danger
For implant holders: Strong magnetic fields affect medical devices. Maintain at least 30 cm distance or request help to handle the magnets.
Fire warning
Drilling and cutting of NdFeB material poses a fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Swallowing risk
Always store magnets away from children. Ingestion danger is high, and the effects of magnets clamping inside the body are tragic.
Demagnetization risk
Avoid heat. Neodymium magnets are susceptible to heat. If you need operation above 80°C, look for HT versions (H, SH, UH).
Cards and drives
Avoid bringing magnets close to a purse, computer, or screen. The magnetic field can irreversibly ruin these devices and wipe information from cards.
Serious injuries
Danger of trauma: The pulling power is so immense that it can result in hematomas, crushing, and even bone fractures. Protective gloves are recommended.
