Advantages and disadvantages of Nd2Fe14B magnets.
Pros
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (according to literature),
- Neodymium magnets are highly resistant to magnetic field loss caused by magnetic disturbances,
- Thanks to the metallic finish, the plating of Ni-Cu-Ni, gold, or silver gives an aesthetic appearance,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of detailed modeling and modifying to specific applications,
- Wide application in future technologies – they find application in HDD drives, brushless drives, medical equipment, as well as other advanced devices.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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 very resistant to heat
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We recommend a housing - magnetic holder, due to difficulties in producing threads inside the magnet and complicated shapes.
- Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Additionally, tiny parts of these magnets can disrupt the diagnostic process medical after entering the body.
- With mass production the cost of neodymium magnets is a challenge,
Lifting parameters
Detachment force of the magnet in optimal conditions – what affects it?
- using a base made of low-carbon steel, serving as a magnetic yoke
- whose thickness reaches at least 10 mm
- characterized by smoothness
- with total lack of distance (no impurities)
- during detachment in a direction perpendicular to the plane
- at room temperature
Practical lifting capacity: influencing factors
- Clearance – the presence of any layer (rust, dirt, air) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel attracts best. Alloy steels reduce magnetic properties and holding force.
- Smoothness – ideal contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and in frost 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 a perpendicular pulling force, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a small distance between the magnet and the plate decreases the holding force.
Safe handling of neodymium magnets
Eye protection
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Bodily injuries
Big blocks can break fingers in a fraction of a second. Do not put your hand between two attracting surfaces.
Electronic hazard
Equipment safety: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, medical aids, timepieces).
GPS and phone interference
Note: neodymium magnets generate a field that confuses precision electronics. Keep a safe distance from your mobile, device, and navigation systems.
Metal Allergy
Some people suffer from a hypersensitivity to Ni, which is the common plating for NdFeB magnets. Frequent touching can result in a rash. We strongly advise use protective gloves.
Adults only
Only for adults. Small elements pose a choking risk, causing severe trauma. Keep away from children and animals.
Thermal limits
Keep cool. NdFeB magnets are sensitive to heat. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
Fire risk
Combustion risk: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.
Powerful field
Handle with care. Neodymium magnets act from a long distance and snap with huge force, often faster than you can move away.
Pacemakers
Medical warning: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
