Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- Their magnetic field is durable, and after approximately ten years it drops only by ~1% (according to research),
- They retain their magnetic properties even under close interference source,
- In other words, due to the smooth layer of nickel, the element gains visual value,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Thanks to freedom in shaping and the capacity to customize to complex applications,
- Significant place in innovative solutions – they serve a role in computer drives, electric motors, medical devices, also industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets decrease their strength 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 durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing threads and complex shapes in magnets, we recommend using cover - magnetic holder.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small components of these magnets can disrupt the diagnostic process medical when they are in the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum lifting capacity of the magnet – what affects it?
- with the contact of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- with a thickness minimum 10 mm
- with an polished touching surface
- with zero gap (no impurities)
- for force acting at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Stainless steels may have worse magnetic properties.
- Smoothness – ideal contact is possible only on polished steel. Rough texture create air cushions, weakening the magnet.
- Thermal environment – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Caution required
Handle magnets consciously. Their immense force can shock even experienced users. Be vigilant and do not underestimate their force.
Heat sensitivity
Avoid heat. NdFeB magnets are sensitive to heat. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
This is not a toy
Adult use only. Tiny parts pose a choking risk, leading to intestinal necrosis. Store out of reach of children and animals.
Physical harm
Danger of trauma: The pulling power is so great that it can result in hematomas, pinching, and broken bones. Use thick gloves.
Fragile material
Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Impact of two magnets leads to them shattering into small pieces.
Life threat
For implant holders: Powerful magnets affect electronics. Keep at least 30 cm distance or ask another person to work with the magnets.
Dust is flammable
Dust created during cutting of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Threat to electronics
Avoid bringing magnets close to a purse, laptop, or TV. The magnetic field can destroy these devices and erase data from cards.
GPS and phone interference
Remember: neodymium magnets generate a field that confuses precision electronics. Keep a safe distance from your mobile, device, and navigation systems.
Nickel allergy
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness happens, cease working with magnets and use protective gear.
