Pros and cons of neodymium magnets.
Strengths
- Their power is maintained, and after approximately 10 years it decreases only by ~1% (theoretically),
- They are resistant to demagnetization induced by presence of other magnetic fields,
- In other words, due to the shiny surface of gold, the element gains visual value,
- Magnets are characterized by exceptionally strong magnetic induction on the outer side,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Thanks to flexibility in designing and the capacity to adapt to specific needs,
- Significant place in innovative solutions – they serve a role in hard drives, motor assemblies, diagnostic systems, and complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium 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 and 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
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We suggest casing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex forms.
- Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, small components of these magnets can disrupt the diagnostic process medical after entering the body.
- With mass production the cost of neodymium magnets can be a barrier,
Pull force analysis
Magnetic strength at its maximum – what affects it?
- with the application of a sheet made of low-carbon steel, ensuring maximum field concentration
- possessing a thickness of minimum 10 mm to avoid saturation
- with a surface perfectly flat
- with direct contact (without coatings)
- during pulling in a direction vertical to the mounting surface
- at temperature room level
What influences lifting capacity in practice
- Gap (between the magnet and the metal), since even a tiny distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Load vector – maximum parameter is reached only during pulling at a 90° angle. The force required to slide of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin plate does not accept the full field, causing part of the flux to be wasted to the other side.
- Metal type – different alloys reacts the same. High carbon content worsen the attraction effect.
- Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
- Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Safety rules for work with NdFeB magnets
Mechanical processing
Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Risk of cracking
NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Collision of two magnets will cause them cracking into shards.
Safe distance
Very strong magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Stay away of at least 10 cm.
This is not a toy
Only for adults. Tiny parts can be swallowed, causing serious injuries. Keep out of reach of kids and pets.
Operating temperature
Keep cool. NdFeB magnets are susceptible to heat. If you need operation above 80°C, look for HT versions (H, SH, UH).
Threat to navigation
Be aware: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your mobile, tablet, and navigation systems.
Handling rules
Handle magnets consciously. Their immense force can surprise even professionals. Stay alert and do not underestimate their force.
ICD Warning
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Nickel coating and allergies
It is widely known that nickel (standard magnet coating) is a common allergen. If you have an allergy, avoid touching magnets with bare hands or choose coated magnets.
Physical harm
Protect your hands. Two large magnets will join immediately with a force of several hundred kilograms, destroying anything in their path. Be careful!
