Pros as well as cons of Nd2Fe14B magnets.
Benefits
- Their power remains stable, and after approximately 10 years it drops only by ~1% (according to research),
- Magnets very well resist against loss of magnetization caused by foreign field sources,
- By applying a reflective layer of gold, the element gains an elegant look,
- Neodymium magnets ensure maximum magnetic induction on a small surface, which increases force concentration,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to modularity in designing and the ability to modify to individual projects,
- Huge importance in modern technologies – they are commonly used in hard drives, electric drive systems, precision medical tools, also modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and 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 recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Limited ability of creating nuts in the magnet and complicated forms - preferred is cover - mounting mechanism.
- Health risk related to microscopic parts of magnets are risky, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small components of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- Due to complex production process, their price exceeds standard values,
Lifting parameters
Detachment force of the magnet in optimal conditions – what contributes to it?
- with the use of a sheet made of special test steel, ensuring full magnetic saturation
- whose thickness is min. 10 mm
- characterized by lack of roughness
- without the slightest clearance between the magnet and steel
- under perpendicular force vector (90-degree angle)
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Steel type – mild steel gives the best results. Alloy admixtures reduce magnetic properties and lifting capacity.
- Surface quality – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Warnings
Keep away from electronics
GPS units and mobile phones are extremely sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Data carriers
Do not bring magnets near a wallet, computer, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Medical interference
People with a pacemaker have to keep an large gap from magnets. The magnetism can interfere with the operation of the implant.
Fire warning
Dust produced during grinding of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Warning for allergy sufferers
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction appears, cease handling magnets and wear gloves.
Power loss in heat
Keep cool. NdFeB magnets are susceptible to temperature. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).
Choking Hazard
Strictly keep magnets away from children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are very dangerous.
Hand protection
Danger of trauma: The pulling power is so immense that it can cause hematomas, pinching, and broken bones. Use thick gloves.
Safe operation
Handle magnets with awareness. Their powerful strength can surprise even experienced users. Be vigilant and do not underestimate their force.
Material brittleness
Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
