Pros as well as cons of Nd2Fe14B magnets.
Pros
- Their power remains stable, and after around 10 years it decreases only by ~1% (according to research),
- Neodymium magnets are distinguished by remarkably resistant to demagnetization caused by external magnetic fields,
- The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnets possess excellent magnetic induction on the outer side,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of custom modeling and optimizing to complex needs,
- Universal use in advanced technology sectors – they are commonly used in hard drives, drive modules, medical devices, and complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- 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
- Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Limited possibility of making nuts in the magnet and complicated shapes - recommended is a housing - magnetic holder.
- Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- on a block made of mild steel, optimally conducting the magnetic flux
- with a cross-section no less than 10 mm
- with a surface cleaned and smooth
- without any air gap between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- in stable room temperature
Impact of factors on magnetic holding capacity in practice
- Distance – the presence of any layer (paint, tape, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Direction of force – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin plate does not accept the full field, causing part of the power to be lost to the other side.
- Metal type – not every steel reacts the same. Alloy additives worsen the attraction effect.
- Surface quality – the more even the surface, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Thermal environment – temperature increase results in weakening of force. Check the thermal limit for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
H&S for magnets
GPS and phone interference
Note: rare earth magnets generate a field that confuses precision electronics. Maintain a safe distance from your phone, device, and GPS.
Maximum temperature
Monitor thermal conditions. Exposing the magnet to high heat will ruin its magnetic structure and strength.
Do not underestimate power
Handle with care. Rare earth magnets act from a distance and connect with massive power, often quicker than you can move away.
Nickel coating and allergies
Studies show that the nickel plating (the usual finish) is a common allergen. For allergy sufferers, avoid touching magnets with bare hands and opt for coated magnets.
Beware of splinters
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Danger to the youngest
Strictly keep magnets out of reach of children. Ingestion danger is significant, and the effects of magnets connecting inside the body are life-threatening.
Electronic hazard
Intense magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Stay away of min. 10 cm.
Pacemakers
Warning for patients: Powerful magnets affect electronics. Keep minimum 30 cm distance or ask another person to handle the magnets.
Do not drill into magnets
Drilling and cutting of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Crushing force
Mind your fingers. Two powerful magnets will snap together instantly with a force of massive weight, destroying everything in their path. Be careful!
