Pros and cons of Nd2Fe14B magnets.
Benefits
- They do not lose magnetism, even during approximately 10 years – the decrease in power is only ~1% (according to tests),
- Magnets effectively protect themselves against demagnetization caused by foreign field sources,
- In other words, due to the smooth finish of nickel, the element is aesthetically pleasing,
- Magnetic induction on the top side of the magnet is very high,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of precise creating and adapting to precise requirements,
- Key role in modern technologies – they are utilized in data components, motor assemblies, advanced medical instruments, as well as technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- At very strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose their power 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Limited possibility of producing threads in the magnet and complex forms - preferred is cover - magnet mounting.
- Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child safety. Furthermore, tiny parts of these magnets are able to be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Best holding force of the magnet in ideal parameters – what contributes to it?
- on a plate made of structural steel, perfectly concentrating the magnetic field
- whose transverse dimension is min. 10 mm
- with an polished touching surface
- with direct contact (no paint)
- during detachment in a direction vertical to the plane
- at conditions approx. 20°C
Lifting capacity in real conditions – factors
- Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Load vector – maximum parameter is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick sheet does not close the flux, causing part of the flux to be lost into the air.
- Material composition – not every steel attracts identically. High carbon content weaken the interaction with the magnet.
- Plate texture – ground elements guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
- Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
Safe handling of NdFeB magnets
Caution required
Before use, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Combustion hazard
Dust generated during machining of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Heat sensitivity
Keep cool. Neodymium magnets are susceptible to temperature. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).
Hand protection
Risk of injury: The attraction force is so immense that it can cause blood blisters, pinching, and broken bones. Protective gloves are recommended.
Magnetic interference
Be aware: rare earth magnets generate a field that disrupts sensitive sensors. Maintain a safe distance from your phone, device, and navigation systems.
Electronic devices
Very strong magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Danger to the youngest
Adult use only. Small elements pose a choking risk, causing intestinal necrosis. Store out of reach of children and animals.
Life threat
Warning for patients: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or request help to handle the magnets.
Allergic reactions
Studies show that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, prevent direct skin contact or opt for coated magnets.
Eye protection
Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
