Advantages and disadvantages of neodymium magnets.
Benefits
- They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (according to literature),
- They show high resistance to demagnetization induced by presence of other magnetic fields,
- Thanks to the smooth finish, the plating of nickel, gold, or silver-plated gives an aesthetic appearance,
- Magnets have huge magnetic induction on the surface,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Possibility of accurate forming and optimizing to defined needs,
- Huge importance in electronics industry – they find application in HDD drives, electric motors, advanced medical instruments, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which enables their usage in compact constructions
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We suggest cover - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complex shapes.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these magnets can be problematic in diagnostics medical when they are in 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 application of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with a surface cleaned and smooth
- without any air gap between the magnet and steel
- under perpendicular application of breakaway force (90-degree angle)
- at ambient temperature room level
Magnet lifting force in use – key factors
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
- Material type – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Temperature influence – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under shearing force the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.
Safe handling of neodymium magnets
Thermal limits
Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Warning for allergy sufferers
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, cease working with magnets and wear gloves.
Life threat
For implant holders: Powerful magnets affect electronics. Keep at least 30 cm distance or request help to handle the magnets.
Handling guide
Be careful. Rare earth magnets attract from a distance and snap with massive power, often faster than you can move away.
Swallowing risk
Always keep magnets out of reach of children. Choking hazard is significant, and the effects of magnets connecting inside the body are tragic.
Magnetic interference
Remember: rare earth magnets produce a field that interferes with precision electronics. Keep a separation from your phone, device, and GPS.
Serious injuries
Large magnets can break fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.
Dust is flammable
Fire warning: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.
Magnetic media
Very strong magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
Magnet fragility
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
