Pros and cons of Nd2Fe14B magnets.
Benefits
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- Neodymium magnets remain exceptionally resistant to demagnetization caused by external field sources,
- The use of an refined layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- They are known for high magnetic induction at the operating surface, which affects their effectiveness,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
- Possibility of individual machining and adjusting to precise conditions,
- Significant place in advanced technology sectors – they are utilized in hard drives, motor assemblies, medical equipment, also technologically advanced constructions.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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 very resistant to heat
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We recommend casing - magnetic mount, due to difficulties in creating nuts inside the magnet and complex shapes.
- Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these products are able to complicate diagnosis medical after entering 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
Detachment force of the magnet in optimal conditions – what affects it?
- using a plate made of high-permeability steel, functioning as a circuit closing element
- possessing a thickness of min. 10 mm to ensure full flux closure
- with a surface perfectly flat
- without the slightest insulating layer between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at conditions approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Clearance – existence of foreign body (rust, dirt, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
- Metal type – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
- Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Uneven metal weaken the grip.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, however under shearing force the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
Precautions when working with NdFeB magnets
Safe operation
Use magnets with awareness. Their powerful strength can surprise even professionals. Plan your moves and do not underestimate their power.
Combustion hazard
Powder created during grinding of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Keep away from electronics
GPS units and mobile phones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
No play value
These products are not suitable for play. Eating multiple magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and requires immediate surgery.
Nickel allergy
Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness occurs, immediately stop handling magnets and wear gloves.
Thermal limits
Keep cool. NdFeB magnets are susceptible to temperature. If you need resistance above 80°C, look for HT versions (H, SH, UH).
ICD Warning
For implant holders: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or request help to work with the magnets.
Keep away from computers
Very strong magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Bodily injuries
Risk of injury: The pulling power is so immense that it can cause blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
Magnets are brittle
NdFeB magnets are sintered ceramics, which means they are fragile like glass. Impact of two magnets will cause them breaking into small pieces.
