Strengths as well as weaknesses of neodymium magnets.
Pros
- Their strength is durable, and after approximately 10 years it drops only by ~1% (according to research),
- They feature excellent resistance to weakening of magnetic properties due to opposing magnetic fields,
- By using a reflective layer of nickel, the element gains an aesthetic look,
- Magnetic induction on the top side of the magnet turns out to be impressive,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to the possibility of precise molding and adaptation to unique needs, NdFeB magnets can be created in a wide range of geometric configurations, which amplifies use scope,
- Versatile presence in modern technologies – they find application in magnetic memories, electric drive systems, diagnostic systems, and multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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 very resistant to heat
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of creating nuts in the magnet and complex forms - recommended is a housing - magnetic holder.
- Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these products are able to disrupt the diagnostic process medical when they are in the body.
- Due to complex production process, their price is higher than average,
Pull force analysis
Detachment force of the magnet in optimal conditions – what it depends on?
- using a plate made of mild steel, serving as a circuit closing element
- whose thickness equals approx. 10 mm
- with an ground touching surface
- under conditions of gap-free contact (surface-to-surface)
- during detachment in a direction perpendicular to the plane
- in neutral thermal conditions
Key elements affecting lifting force
- Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Direction of force – highest force is available only during perpendicular pulling. The shear force of the magnet along the plate is typically several times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Steel type – mild steel attracts best. Alloy admixtures lower magnetic permeability and holding force.
- Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
H&S for magnets
No play value
Absolutely keep magnets away from children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are very dangerous.
Threat to electronics
Avoid bringing magnets near a purse, laptop, or TV. The magnetic field can destroy these devices and wipe information from cards.
Warning for allergy sufferers
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation occurs, cease handling magnets and use protective gear.
Fragile material
Neodymium magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets leads to them breaking into shards.
ICD Warning
Life threat: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Combustion hazard
Powder produced during grinding of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Caution required
Exercise caution. Rare earth magnets attract from a long distance and connect with huge force, often quicker than you can react.
Compass and GPS
GPS units and mobile phones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
Finger safety
Large magnets can break fingers instantly. Never place your hand betwixt two strong magnets.
Power loss in heat
Control the heat. Exposing the magnet to high heat will destroy its properties and pulling force.
