Advantages as well as disadvantages of neodymium magnets.
Benefits
- They retain full power for almost 10 years – the loss is just ~1% (according to analyses),
- They retain their magnetic properties even under close interference source,
- In other words, due to the metallic finish of nickel, the element looks attractive,
- The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of custom shaping and optimizing to specific needs,
- Key role in modern industrial fields – they serve a role in hard drives, drive modules, advanced medical instruments, and complex engineering applications.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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 extremely resistant to heat
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complex forms in magnets, we propose using a housing - magnetic mount.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which becomes key in the context of child safety. Additionally, tiny parts of these devices are able to complicate diagnosis medical in case of swallowing.
- Due to complex production process, their price is relatively high,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what it depends on?
- with the contact of a yoke made of special test steel, guaranteeing full magnetic saturation
- with a cross-section no less than 10 mm
- with an ground touching surface
- without the slightest insulating layer between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- in temp. approx. 20°C
Practical lifting capacity: influencing factors
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Direction of force – maximum parameter is reached only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Material type – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Smoothness – full contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under shearing force the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet and the plate reduces the load capacity.
Safety rules for work with NdFeB magnets
Respect the power
Handle magnets consciously. Their powerful strength can surprise even experienced users. Be vigilant and respect their force.
Allergic reactions
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, immediately stop handling magnets and wear gloves.
Adults only
These products are not toys. Eating multiple magnets can lead to them connecting inside the digestive tract, which poses a direct threat to life and necessitates urgent medical intervention.
Hand protection
Protect your hands. Two large magnets will snap together instantly with a force of several hundred kilograms, destroying anything in their path. Be careful!
Safe distance
Equipment safety: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, timepieces).
Material brittleness
Protect your eyes. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
Dust is flammable
Mechanical processing of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Implant safety
Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Demagnetization risk
Control the heat. Exposing the magnet to high heat will destroy its properties and strength.
Compass and GPS
Note: rare earth magnets generate a field that disrupts precision electronics. Keep a separation from your mobile, tablet, and navigation systems.
