Pros and cons of Nd2Fe14B magnets.
Benefits
- They have unchanged lifting capacity, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
- They have excellent resistance to magnetism drop as a result of external magnetic sources,
- Thanks to the elegant finish, the surface of Ni-Cu-Ni, gold-plated, or silver gives an clean appearance,
- Neodymium magnets deliver maximum magnetic induction on a small area, which allows for strong attraction,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of precise machining and modifying to defined requirements,
- Versatile presence in advanced technology sectors – they serve a role in hard drives, electric motors, precision medical tools, and other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Limitations
- At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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 extremely resistant to heat
- They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complicated shapes in magnets, we recommend using a housing - magnetic holder.
- Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products can complicate diagnosis medical after entering the body.
- Due to expensive raw materials, their price is relatively high,
Pull force analysis
Maximum holding power of the magnet – what it depends on?
- with the use of a yoke made of special test steel, guaranteeing full magnetic saturation
- whose transverse dimension equals approx. 10 mm
- with a plane free of scratches
- without any insulating layer between the magnet and steel
- under vertical application of breakaway force (90-degree angle)
- in neutral thermal conditions
Impact of factors on magnetic holding capacity in practice
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Steel type – low-carbon steel gives the best results. Alloy steels decrease magnetic properties and lifting capacity.
- Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
- Temperature – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, in contrast under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate decreases the lifting capacity.
H&S for magnets
Keep away from electronics
Navigation devices and smartphones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
Allergic reactions
Allergy Notice: The nickel-copper-nickel coating contains nickel. If redness appears, cease working with magnets and wear gloves.
Electronic devices
Intense magnetic fields can erase data on payment cards, hard drives, and storage devices. Stay away of min. 10 cm.
Keep away from children
These products are not toys. Accidental ingestion of several magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and necessitates urgent medical intervention.
Caution required
Before use, read the rules. Sudden snapping can break the magnet or injure your hand. Be predictive.
Fire warning
Machining of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Operating temperature
Monitor thermal conditions. Heating the magnet to high heat will permanently weaken its magnetic structure and strength.
Serious injuries
Danger of trauma: The attraction force is so immense that it can result in hematomas, pinching, and even bone fractures. Use thick gloves.
Shattering risk
Watch out for shards. Magnets can explode upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.
Implant safety
Health Alert: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
