Strengths and weaknesses of neodymium magnets.
Strengths
- They have unchanged lifting capacity, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
- They feature excellent resistance to weakening of magnetic properties due to external magnetic sources,
- By applying a shiny coating of silver, the element gains an proper look,
- Neodymium magnets achieve maximum magnetic induction on a small area, which increases force concentration,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of precise modeling and optimizing to atypical requirements,
- Key role in modern industrial fields – they are used in data components, electric drive systems, precision medical tools, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in compact constructions
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as 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 rust. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We suggest cover - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex shapes.
- Health risk to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. Additionally, small components of these devices can be problematic in diagnostics medical when they are in the body.
- Due to expensive raw materials, their price is relatively high,
Lifting parameters
Maximum lifting capacity of the magnet – what affects it?
- on a base made of structural steel, perfectly concentrating the magnetic flux
- whose transverse dimension reaches at least 10 mm
- characterized by even structure
- under conditions of gap-free contact (metal-to-metal)
- under vertical force direction (90-degree angle)
- at room temperature
Practical aspects of lifting capacity – factors
- Clearance – the presence of foreign body (paint, dirt, air) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys attracts identically. High carbon content worsen the attraction effect.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under shearing force the holding force is lower. In addition, even a small distance between the magnet and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
Mechanical processing
Powder generated during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Medical implants
People with a heart stimulator have to maintain an absolute distance from magnets. The magnetism can stop the operation of the life-saving device.
Power loss in heat
Do not overheat. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, ask us about HT versions (H, SH, UH).
Safe operation
Handle magnets consciously. Their huge power can shock even professionals. Stay alert and do not underestimate their force.
Safe distance
Data protection: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
Allergic reactions
It is widely known that nickel (standard magnet coating) is a common allergen. If you have an allergy, refrain from touching magnets with bare hands or opt for encased magnets.
GPS Danger
Be aware: rare earth magnets generate a field that interferes with sensitive sensors. Maintain a safe distance from your phone, tablet, and GPS.
Pinching danger
Protect your hands. Two powerful magnets will snap together instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!
Product not for children
Product intended for adults. Tiny parts can be swallowed, causing serious injuries. Keep away from children and animals.
Shattering risk
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
