Advantages as well as disadvantages of neodymium magnets.
Advantages
- They do not lose strength, even over around 10 years – the reduction in power is only ~1% (theoretically),
- They feature excellent resistance to magnetic field loss due to opposing magnetic fields,
- Thanks to the shimmering finish, the plating of nickel, gold-plated, or silver-plated gives an visually attractive appearance,
- They are known for high magnetic induction at the operating surface, which improves attraction properties,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to the option of flexible forming and customization to specialized requirements, magnetic components can be modeled in a wide range of forms and dimensions, which increases their versatility,
- Key role in electronics industry – they are used in hard drives, motor assemblies, diagnostic systems, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in small systems
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their durability
- Neodymium magnets demagnetize 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
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- Due to limitations in producing nuts and complex shapes in magnets, we propose using a housing - magnetic mount.
- Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child health protection. It is also worth noting that small elements of these magnets can be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Maximum magnetic pulling force – what affects it?
- on a base made of structural steel, effectively closing the magnetic flux
- whose transverse dimension equals approx. 10 mm
- with a surface perfectly flat
- without any insulating layer between the magnet and steel
- under perpendicular force direction (90-degree angle)
- at temperature room level
Lifting capacity in real conditions – factors
- Distance – the presence of foreign body (rust, dirt, air) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Base massiveness – insufficiently thick sheet does not close the flux, causing part of the flux to be escaped into the air.
- Material composition – different alloys attracts identically. High carbon content worsen the attraction effect.
- Surface finish – full contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under perpendicular forces, whereas under shearing force the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
Data carriers
Data protection: Neodymium magnets can damage payment cards and sensitive devices (heart implants, medical aids, mechanical watches).
Health Danger
Individuals with a heart stimulator should maintain an absolute distance from magnets. The magnetic field can stop the functioning of the implant.
Safe operation
Handle magnets consciously. Their huge power can surprise even professionals. Plan your moves and respect their force.
Maximum temperature
Watch the temperature. Heating the magnet to high heat will permanently weaken its properties and strength.
Machining danger
Powder generated during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Avoid contact if allergic
Some people suffer from a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Frequent touching might lead to an allergic reaction. We suggest use protective gloves.
Do not give to children
These products are not suitable for play. Accidental ingestion of several magnets can lead to them pinching intestinal walls, which poses a severe health hazard and necessitates urgent medical intervention.
Material brittleness
Protect your eyes. Magnets can explode upon violent connection, ejecting shards into the air. We recommend safety glasses.
Bone fractures
Large magnets can smash fingers in a fraction of a second. Do not place your hand betwixt two attracting surfaces.
GPS and phone interference
A strong magnetic field disrupts the functioning of compasses in phones and GPS navigation. Maintain magnets near a smartphone to avoid breaking the sensors.
