Pros and cons of Nd2Fe14B magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (in laboratory conditions),
- Neodymium magnets prove to be extremely resistant to loss of magnetic properties caused by external field sources,
- The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnets are characterized by maximum magnetic induction on the working surface,
- Neodymium magnets are characterized by extremely 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...
- Thanks to modularity in designing and the ability to customize to specific needs,
- Fundamental importance in future technologies – they are utilized in data components, motor assemblies, medical devices, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in compact constructions
Limitations
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also raises their durability
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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 extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Limited ability of creating nuts in the magnet and complex forms - recommended is a housing - magnet mounting.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child safety. Furthermore, tiny parts of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Maximum magnetic pulling force – what affects it?
- with the contact of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- possessing a thickness of at least 10 mm to avoid saturation
- with a plane free of scratches
- under conditions of ideal adhesion (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- in neutral thermal conditions
Practical lifting capacity: influencing factors
- Clearance – the presence of foreign body (paint, tape, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Material composition – not every steel reacts the same. Alloy additives weaken the attraction effect.
- Surface finish – ideal contact is obtained only on smooth steel. Rough texture create air cushions, reducing force.
- Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, however under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate lowers the load capacity.
Warnings
Threat to electronics
Very strong magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.
Health Danger
Life threat: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Machining danger
Combustion risk: Rare earth powder is explosive. Avoid machining magnets without safety gear as this may cause fire.
Thermal limits
Avoid heat. NdFeB magnets are sensitive to temperature. If you need operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Immense force
Handle magnets with awareness. Their immense force can shock even experienced users. Be vigilant and do not underestimate their power.
Danger to the youngest
NdFeB magnets are not suitable for play. Accidental ingestion of a few magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and requires immediate surgery.
Avoid contact if allergic
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If redness appears, immediately stop handling magnets and use protective gear.
Keep away from electronics
GPS units and smartphones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
Physical harm
Protect your hands. Two powerful magnets will join instantly with a force of massive weight, destroying anything in their path. Be careful!
Risk of cracking
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
