Pros and cons of neodymium magnets.
Strengths
- They have unchanged lifting capacity, and over nearly 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They possess excellent resistance to magnetism drop as a result of external magnetic sources,
- The use of an refined layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnets possess excellent magnetic induction on the outer layer,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to the option of precise shaping and adaptation to custom needs, NdFeB magnets can be modeled in a broad palette of geometric configurations, which increases their versatility,
- Wide application in advanced technology sectors – they find application in computer drives, drive modules, medical equipment, and technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Disadvantages
- To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets decrease their power 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
- 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 suggest cover - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complex forms.
- Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, small elements of these magnets are able to be problematic in diagnostics medical after entering the body.
- With large orders the cost of neodymium magnets is a challenge,
Pull force analysis
Maximum magnetic pulling force – what affects it?
- with the use of a sheet made of low-carbon steel, ensuring full magnetic saturation
- whose transverse dimension reaches at least 10 mm
- with a surface free of scratches
- under conditions of ideal adhesion (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Distance (between the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Plate thickness – insufficiently thick plate does not close the flux, causing part of the power to be lost to the other side.
- Material type – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
- Surface structure – the more even the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Temperature – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under shearing force the holding force is lower. Moreover, even a small distance between the magnet and the plate lowers the load capacity.
Safe handling of NdFeB magnets
Demagnetization risk
Avoid heat. Neodymium magnets are susceptible to heat. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Precision electronics
Note: neodymium magnets generate a field that confuses sensitive sensors. Maintain a separation from your phone, device, and GPS.
Fire risk
Combustion risk: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.
Do not give to children
Absolutely store magnets away from children. Risk of swallowing is high, and the effects of magnets clamping inside the body are life-threatening.
Safe distance
Avoid bringing magnets near a purse, laptop, or TV. The magnetic field can permanently damage these devices and erase data from cards.
Eye protection
Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
Conscious usage
Handle with care. Neodymium magnets act from a distance and snap with massive power, often faster than you can move away.
Hand protection
Pinching hazard: The attraction force is so immense that it can cause hematomas, pinching, and broken bones. Protective gloves are recommended.
Warning for heart patients
Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Sensitization to coating
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation occurs, cease working with magnets and wear gloves.
