Pros and cons of Nd2Fe14B magnets.
Strengths
- They retain full power for almost ten years – the loss is just ~1% (based on simulations),
- They do not lose their magnetic properties even under close interference source,
- The use of an refined coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Thanks to flexibility in constructing and the ability to modify to unusual requirements,
- Universal use in high-tech industry – they are used in magnetic memories, brushless drives, precision medical tools, and modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in miniature devices
Disadvantages
- At very strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- Due to limitations in realizing threads and complex forms in magnets, we propose using casing - magnetic mount.
- Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these products can disrupt the diagnostic process medical when they are in the body.
- Due to expensive raw materials, their price exceeds standard values,
Lifting parameters
Magnetic strength at its maximum – what affects it?
- on a base made of structural steel, perfectly concentrating the magnetic flux
- whose thickness equals approx. 10 mm
- characterized by smoothness
- without any air gap between the magnet and steel
- under vertical force direction (90-degree angle)
- at standard ambient temperature
Practical lifting capacity: influencing factors
- Air gap (betwixt the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Chemical composition of the base – mild steel gives the best results. Alloy steels reduce magnetic properties and lifting capacity.
- Surface quality – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal environment – heating the magnet causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Warnings
Beware of splinters
Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Keep away from children
NdFeB magnets are not suitable for play. Accidental ingestion of a few magnets can lead to them pinching intestinal walls, which constitutes a direct threat to life and necessitates urgent medical intervention.
Precision electronics
Note: rare earth magnets generate a field that interferes with precision electronics. Maintain a separation from your phone, tablet, and navigation systems.
Conscious usage
Use magnets consciously. Their powerful strength can shock even experienced users. Plan your moves and respect their power.
Protect data
Intense magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.
Danger to pacemakers
Life threat: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Skin irritation risks
Certain individuals suffer from a sensitization to Ni, which is the standard coating for neodymium magnets. Prolonged contact might lead to an allergic reaction. We suggest wear safety gloves.
Do not overheat magnets
Avoid heat. NdFeB magnets are sensitive to heat. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
Pinching danger
Risk of injury: The pulling power is so great that it can result in hematomas, crushing, and broken bones. Use thick gloves.
Flammability
Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
