Strengths as well as weaknesses of Nd2Fe14B magnets.
Advantages
- They have stable power, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
- Magnets effectively defend themselves against loss of magnetization caused by external fields,
- By using a lustrous layer of gold, the element presents an aesthetic look,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of precise shaping as well as optimizing to precise requirements,
- Versatile presence in high-tech industry – they are utilized in HDD drives, drive modules, precision medical tools, and complex engineering applications.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Weaknesses
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium 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
- They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited ability of producing threads in the magnet and complicated forms - preferred is casing - magnetic holder.
- Possible danger to health – tiny shards of magnets are risky, when accidentally swallowed, which is particularly important in the context of child safety. Furthermore, small elements of these devices can disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Maximum lifting capacity of the magnet – what it depends on?
- with the contact of a sheet made of special test steel, ensuring full magnetic saturation
- with a cross-section no less than 10 mm
- characterized by lack of roughness
- under conditions of gap-free contact (surface-to-surface)
- for force applied at a right angle (pull-off, not shear)
- at temperature room level
Key elements affecting lifting force
- Space between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Steel thickness – too thin steel does not close the flux, causing part of the power to be wasted into the air.
- Chemical composition of the base – mild steel gives the best results. Alloy admixtures reduce magnetic properties and holding force.
- Surface quality – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the holding force is lower. In addition, even a small distance between the magnet and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
Allergic reactions
It is widely known that nickel (the usual finish) is a potent allergen. If you have an allergy, avoid direct skin contact and select encased magnets.
Magnetic media
Equipment safety: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, medical aids, mechanical watches).
Pinching danger
Watch your fingers. Two powerful magnets will join immediately with a force of massive weight, crushing everything in their path. Be careful!
Danger to pacemakers
People with a heart stimulator must maintain an absolute distance from magnets. The magnetism can interfere with the functioning of the implant.
Choking Hazard
Strictly store magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are very dangerous.
Caution required
Before starting, read the rules. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Maximum temperature
Watch the temperature. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and strength.
Risk of cracking
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
Combustion hazard
Dust created during machining of magnets is combustible. Do not drill into magnets unless you are an expert.
Threat to navigation
GPS units and smartphones are highly susceptible to magnetism. Direct contact with a strong magnet can permanently damage the sensors in your phone.
