Pros and cons of Nd2Fe14B magnets.
Advantages
- They do not lose strength, even after nearly ten years – the drop in strength is only ~1% (theoretically),
- Magnets effectively defend themselves against loss of magnetization caused by ambient magnetic noise,
- Thanks to the reflective finish, the surface of nickel, gold-plated, or silver-plated gives an aesthetic appearance,
- Magnetic induction on the top side of the magnet is very high,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to versatility in forming and the capacity to customize to unusual requirements,
- Significant place in electronics industry – they find application in hard drives, brushless drives, advanced medical instruments, and industrial machines.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Cons
- To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Limited possibility of producing threads in the magnet and complex shapes - recommended is casing - mounting mechanism.
- Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small components of these devices can be problematic in diagnostics medical when they are in the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Holding force characteristics
Magnetic strength at its maximum – what contributes to it?
- on a base made of mild steel, effectively closing the magnetic flux
- with a thickness no less than 10 mm
- with a plane cleaned and smooth
- under conditions of ideal adhesion (metal-to-metal)
- during detachment in a direction vertical to the mounting surface
- at standard ambient temperature
Determinants of practical lifting force of a magnet
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Load vector – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Steel type – low-carbon steel gives the best results. Higher carbon content reduce magnetic properties and holding force.
- Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the holding force is lower. In addition, even a slight gap between the magnet and the plate reduces the holding force.
Safety rules for work with neodymium magnets
Fire warning
Drilling and cutting of neodymium magnets poses a fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Operating temperature
Do not overheat. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).
Protect data
Do not bring magnets near a purse, computer, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
Phone sensors
Remember: rare earth magnets generate a field that confuses sensitive sensors. Maintain a separation from your phone, tablet, and GPS.
Magnet fragility
Watch out for shards. Magnets can explode upon violent connection, ejecting shards into the air. Eye protection is mandatory.
No play value
NdFeB magnets are not toys. Accidental ingestion of a few magnets can lead to them connecting inside the digestive tract, which poses a critical condition and requires immediate surgery.
Powerful field
Handle magnets consciously. Their powerful strength can shock even professionals. Be vigilant and respect their force.
Finger safety
Danger of trauma: The pulling power is so great that it can result in blood blisters, crushing, and broken bones. Protective gloves are recommended.
Medical interference
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
Allergy Warning
Studies show that nickel (the usual finish) is a strong allergen. If your skin reacts to metals, prevent direct skin contact and select versions in plastic housing.
