Pros as well as cons of neodymium magnets.
Benefits
- They do not lose strength, even during approximately 10 years – the decrease in strength is only ~1% (according to tests),
- They do not lose their magnetic properties even under close interference source,
- In other words, due to the smooth layer of gold, the element is aesthetically pleasing,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures reaching 230°C and above...
- Considering the ability of precise shaping and adaptation to specialized needs, neodymium magnets can be modeled in a broad palette of geometric configurations, which expands the range of possible applications,
- Universal use in high-tech industry – they are utilized in HDD drives, electric drive systems, advanced medical instruments, and modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in miniature devices
Weaknesses
- At strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Limited ability of producing nuts in the magnet and complicated shapes - recommended is cover - magnet mounting.
- Potential hazard related to microscopic parts of magnets are risky, if swallowed, which becomes key in the context of child health protection. It is also worth noting that small elements of these products can complicate diagnosis medical when they are in the body.
- Due to complex production process, their price is higher than average,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what affects it?
- using a plate made of mild steel, acting as a circuit closing element
- with a thickness of at least 10 mm
- characterized by even structure
- under conditions of ideal adhesion (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- at conditions approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Gap (between the magnet and the metal), since even a microscopic distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
- Load vector – maximum parameter is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Steel grade – ideal substrate is pure iron steel. Hardened steels may attract less.
- Surface finish – ideal contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
- Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
H&S for magnets
Keep away from electronics
Be aware: rare earth magnets produce a field that confuses precision electronics. Maintain a safe distance from your mobile, device, and navigation systems.
Safe operation
Before use, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Bodily injuries
Big blocks can smash fingers in a fraction of a second. Under no circumstances place your hand betwixt two strong magnets.
Fire warning
Powder generated during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Product not for children
Neodymium magnets are not toys. Swallowing several magnets may result in them pinching intestinal walls, which constitutes a critical condition and necessitates immediate surgery.
Avoid contact if allergic
Some people experience a hypersensitivity to Ni, which is the common plating for NdFeB magnets. Prolonged contact might lead to dermatitis. We strongly advise wear protective gloves.
Magnets are brittle
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Medical interference
Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Safe distance
Do not bring magnets close to a wallet, computer, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Maximum temperature
Standard neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
