Pros as well as cons of Nd2Fe14B magnets.
Strengths
- They do not lose strength, even during approximately 10 years – the drop in power is only ~1% (theoretically),
- They do not lose their magnetic properties even under close interference source,
- Thanks to the smooth finish, the surface of Ni-Cu-Ni, gold, or silver gives an visually attractive appearance,
- The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Considering the potential of flexible molding and adaptation to custom solutions, neodymium magnets can be created in a variety of geometric configurations, which increases their versatility,
- Huge importance in modern technologies – they serve a role in data components, motor assemblies, medical equipment, also technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Limitations
- To avoid cracks upon strong impacts, we recommend using special steel housings. 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
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in creating threads and complex shapes in magnets, we recommend using casing - magnetic mount.
- Possible danger related to microscopic parts of magnets are risky, if swallowed, which becomes key in the context of child health protection. Additionally, small elements of these products can complicate diagnosis medical when they are in the body.
- With mass production the cost of neodymium magnets can be a barrier,
Lifting parameters
Best holding force of the magnet in ideal parameters – what contributes to it?
- on a base made of mild steel, optimally conducting the magnetic flux
- whose transverse dimension reaches at least 10 mm
- with a plane free of scratches
- under conditions of gap-free contact (surface-to-surface)
- during pulling in a direction perpendicular to the plane
- at conditions approx. 20°C
Lifting capacity in real conditions – factors
- Air gap (between the magnet and the plate), because even a microscopic clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Plate material – low-carbon steel attracts best. Alloy admixtures lower magnetic properties and lifting capacity.
- Base smoothness – the more even the plate, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a small distance between the magnet and the plate decreases the holding force.
H&S for magnets
Flammability
Powder created during grinding of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Keep away from children
Absolutely keep magnets away from children. Choking hazard is high, and the effects of magnets connecting inside the body are life-threatening.
Magnets are brittle
Neodymium magnets are ceramic materials, meaning they are very brittle. Impact of two magnets leads to them shattering into shards.
Nickel allergy
Certain individuals suffer from a sensitization to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching may cause dermatitis. We suggest use safety gloves.
Immense force
Handle with care. Rare earth magnets act from a distance and snap with huge force, often quicker than you can move away.
Magnetic media
Data protection: Strong magnets can ruin payment cards and sensitive devices (heart implants, medical aids, mechanical watches).
Pinching danger
Pinching hazard: The pulling power is so great that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.
Keep away from electronics
Be aware: rare earth magnets generate a field that disrupts sensitive sensors. Maintain a safe distance from your phone, tablet, and navigation systems.
Permanent damage
Do not overheat. Neodymium magnets are sensitive to heat. If you require resistance above 80°C, look for HT versions (H, SH, UH).
ICD Warning
Life threat: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
