Other offers
Pros as well as cons of Nd2Fe14B magnets.
Advantages
- They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
- They are noted for resistance to demagnetization induced by external disturbances,
- In other words, due to the metallic surface of nickel, the element becomes visually attractive,
- Magnetic induction on the top side of the magnet turns out to be maximum,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to flexibility in shaping and the capacity to adapt to unusual requirements,
- Wide application in future technologies – they are used in computer drives, motor assemblies, medical devices, and other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Limited ability of making nuts in the magnet and complex shapes - preferred is cover - magnetic holder.
- Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these devices are able to be problematic in diagnostics medical after entering the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what affects it?
- using a sheet made of low-carbon steel, serving as a circuit closing element
- whose thickness reaches at least 10 mm
- with an polished contact surface
- with total lack of distance (no coatings)
- under vertical force direction (90-degree angle)
- at room temperature
Impact of factors on magnetic holding capacity in practice
- Distance – existence of foreign body (rust, dirt, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is obtained only during perpendicular pulling. The shear force of the magnet along the surface is usually many times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Metal type – not every steel reacts the same. High carbon content worsen the attraction effect.
- Surface quality – the smoother and more polished the surface, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Temperature influence – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet and the plate decreases the lifting capacity.
Safe handling of neodymium magnets
Mechanical processing
Drilling and cutting of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Physical harm
Protect your hands. Two powerful magnets will snap together immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Thermal limits
Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Data carriers
Very strong magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Stay away of at least 10 cm.
Handling rules
Handle magnets consciously. Their immense force can shock even experienced users. Plan your moves and respect their force.
GPS and phone interference
GPS units and mobile phones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Product not for children
Adult use only. Small elements can be swallowed, causing serious injuries. Store out of reach of children and animals.
Fragile material
Despite metallic appearance, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Danger to pacemakers
Health Alert: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Allergy Warning
Nickel alert: The nickel-copper-nickel coating contains nickel. If skin irritation occurs, immediately stop working with magnets and wear gloves.
