Pros as well as cons of Nd2Fe14B magnets.
Benefits
- They do not lose power, even during nearly ten years – the decrease in strength is only ~1% (theoretically),
- They feature excellent resistance to magnetic field loss as a result of external magnetic sources,
- The use of an metallic finish 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, making them more effective,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the ability of accurate shaping and adaptation to unique needs, neodymium magnets can be produced in a variety of geometric configurations, which increases their versatility,
- Significant place in future technologies – they serve a role in data components, electromotive mechanisms, precision medical tools, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in small systems
Limitations
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
- We recommend casing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex forms.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which gains importance in the context of child health protection. Furthermore, small elements of these magnets can complicate diagnosis medical after entering the body.
- Due to expensive raw materials, their price exceeds standard values,
Pull force analysis
Maximum holding power of the magnet – what affects it?
- using a plate made of low-carbon steel, functioning as a ideal flux conductor
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with an polished touching surface
- with zero gap (without coatings)
- under vertical force direction (90-degree angle)
- at conditions approx. 20°C
Practical aspects of lifting capacity – factors
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Plate material – low-carbon steel gives the best results. Alloy steels reduce magnetic permeability and lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
- Thermal environment – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity was measured with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Dust is flammable
Fire warning: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Nickel allergy
It is widely known that nickel (standard magnet coating) is a strong allergen. If your skin reacts to metals, prevent direct skin contact or choose versions in plastic housing.
Medical implants
Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Caution required
Use magnets consciously. Their immense force can shock even experienced users. Plan your moves and respect their power.
Danger to the youngest
These products are not intended for children. Eating several magnets can lead to them pinching intestinal walls, which poses a critical condition and necessitates urgent medical intervention.
Thermal limits
Avoid heat. NdFeB magnets are susceptible to temperature. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).
Beware of splinters
Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
Electronic hazard
Data protection: Strong magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, timepieces).
Keep away from electronics
Note: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a separation from your phone, tablet, and GPS.
Physical harm
Big blocks can crush fingers in a fraction of a second. Never put your hand between two strong magnets.
