Strengths and weaknesses of neodymium magnets.
Pros
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (based on calculations),
- Neodymium magnets remain remarkably resistant to loss of magnetic properties caused by external field sources,
- Thanks to the shimmering finish, the surface of Ni-Cu-Ni, gold-plated, or silver gives an modern appearance,
- Neodymium magnets create maximum magnetic induction on a small area, which increases force concentration,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures reaching 230°C and above...
- In view of the possibility of precise shaping and adaptation to custom projects, magnetic components can be modeled in a wide range of shapes and sizes, which amplifies use scope,
- Key role in electronics industry – they serve a role in hard drives, motor assemblies, medical devices, and complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
- NdFeB magnets demagnetize 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 very resistant to heat
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited possibility of making nuts in the magnet and complex shapes - recommended is a housing - magnetic holder.
- Health risk to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. Additionally, tiny parts of these magnets can disrupt the diagnostic process medical in case of swallowing.
- Due to expensive raw materials, their price exceeds standard values,
Pull force analysis
Maximum holding power of the magnet – what affects it?
- on a plate made of structural steel, perfectly concentrating the magnetic flux
- possessing a massiveness of at least 10 mm to avoid saturation
- characterized by lack of roughness
- with total lack of distance (without impurities)
- for force applied at a right angle (in the magnet axis)
- at temperature room level
Magnet lifting force in use – key factors
- Clearance – existence of foreign body (paint, dirt, gap) acts as an insulator, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity 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 converting into lifting capacity.
- Material type – the best choice is pure iron steel. Hardened steels may attract less.
- Smoothness – full contact is possible only on polished steel. Rough texture create air cushions, reducing force.
- Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet and the plate reduces the lifting capacity.
H&S for magnets
Dust is flammable
Dust created during grinding of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Shattering risk
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
This is not a toy
Absolutely store magnets out of reach of children. Choking hazard is high, and the effects of magnets connecting inside the body are very dangerous.
Safe distance
Avoid bringing magnets close to a wallet, computer, or screen. The magnetic field can permanently damage these devices and erase data from cards.
Hand protection
Watch your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!
Keep away from electronics
GPS units and smartphones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.
Powerful field
Before starting, read the rules. Sudden snapping can break the magnet or injure your hand. Be predictive.
Health Danger
Life threat: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Maximum temperature
Avoid heat. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Sensitization to coating
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness happens, immediately stop handling magnets and use protective gear.
