Advantages as well as disadvantages of Nd2Fe14B magnets.
Benefits
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- They are noted for resistance to demagnetization induced by external disturbances,
- Thanks to the elegant finish, the layer of nickel, gold, or silver-plated gives an modern appearance,
- Magnetic induction on the working layer of the magnet remains very high,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Considering the possibility of accurate shaping and customization to unique solutions, NdFeB magnets can be created in a variety of shapes and sizes, which increases their versatility,
- Universal use in modern industrial fields – they find application in hard drives, brushless drives, diagnostic systems, also industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- At very strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We recommend a housing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, small elements of these devices are able to be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- on a base made of mild steel, effectively closing the magnetic field
- whose thickness is min. 10 mm
- characterized by lack of roughness
- with direct contact (without coatings)
- during pulling in a direction perpendicular to the plane
- in neutral thermal conditions
Key elements affecting lifting force
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Base massiveness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be escaped into the air.
- Metal type – not every steel attracts identically. High carbon content weaken the interaction with the magnet.
- Surface quality – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate lowers the holding force.
Safe handling of NdFeB magnets
Risk of cracking
Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.
Warning for allergy sufferers
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation appears, cease working with magnets and wear gloves.
Flammability
Combustion risk: Neodymium dust is highly flammable. Do not process magnets without safety gear as this may cause fire.
Precision electronics
Navigation devices and mobile phones are extremely sensitive to magnetic fields. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
Pinching danger
Risk of injury: The attraction force is so immense that it can cause hematomas, pinching, and even bone fractures. Use thick gloves.
Heat sensitivity
Keep cool. NdFeB magnets are susceptible to heat. If you require operation above 80°C, inquire about HT versions (H, SH, UH).
Do not underestimate power
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
No play value
Neodymium magnets are not suitable for play. Swallowing a few magnets may result in them connecting inside the digestive tract, which poses a critical condition and necessitates urgent medical intervention.
Health Danger
Medical warning: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Cards and drives
Do not bring magnets near a purse, computer, or screen. The magnetism can permanently damage these devices and erase data from cards.
