Pros as well as cons of Nd2Fe14B magnets.
Strengths
- They have constant strength, and over nearly ten years their performance decreases symbolically – ~1% (according to theory),
- Neodymium magnets are characterized by highly resistant to demagnetization caused by external field sources,
- In other words, due to the reflective finish of silver, the element becomes visually attractive,
- The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures reaching 230°C and above...
- Due to the option of flexible molding and adaptation to specialized requirements, NdFeB magnets can be manufactured in a variety of shapes and sizes, which expands the range of possible applications,
- Huge importance in modern technologies – they are commonly used in magnetic memories, electric motors, medical devices, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in small systems
Disadvantages
- To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets lose their force 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
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complicated forms in magnets, we recommend using cover - magnetic holder.
- Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. It is also worth noting that tiny parts of these magnets can be problematic in diagnostics medical when they are in the body.
- With mass production the cost of neodymium magnets is economically unviable,
Pull force analysis
Magnetic strength at its maximum – what it depends on?
- using a base made of low-carbon steel, functioning as a magnetic yoke
- with a thickness of at least 10 mm
- characterized by smoothness
- without any insulating layer between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at conditions approx. 20°C
Lifting capacity in practice – influencing factors
- Distance – the presence of foreign body (rust, tape, air) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Load vector – maximum parameter is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin steel does not accept the full field, causing part of the flux to be escaped into the air.
- Metal type – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
- Smoothness – ideal contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal environment – temperature increase results in weakening of force. Check the thermal limit for a given model.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, however under attempts to slide the magnet the holding force is lower. Moreover, even a small distance between the magnet and the plate reduces the holding force.
Warnings
Avoid contact if allergic
Certain individuals have a hypersensitivity to nickel, which is the common plating for neodymium magnets. Extended handling may cause skin redness. We suggest wear safety gloves.
Cards and drives
Do not bring magnets close to a wallet, laptop, or TV. The magnetism can destroy these devices and erase data from cards.
No play value
These products are not toys. Swallowing a few magnets may result in them pinching intestinal walls, which poses a severe health hazard and requires urgent medical intervention.
ICD Warning
For implant holders: Powerful magnets disrupt medical devices. Maintain at least 30 cm distance or request help to handle the magnets.
Handling guide
Be careful. Neodymium magnets attract from a long distance and snap with huge force, often quicker than you can react.
Fire warning
Machining of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Impact on smartphones
Be aware: rare earth magnets produce a field that confuses precision electronics. Keep a safe distance from your phone, tablet, and navigation systems.
Hand protection
Big blocks can smash fingers instantly. Never place your hand betwixt two strong magnets.
Eye protection
Neodymium magnets are ceramic materials, which means they are very brittle. Clashing of two magnets will cause them shattering into shards.
Do not overheat magnets
Standard neodymium magnets (grade N) lose power when the temperature goes above 80°C. The loss of strength is permanent.
