Strengths and weaknesses of Nd2Fe14B magnets.
Strengths
- They do not lose strength, even after around ten years – the decrease in lifting capacity is only ~1% (according to tests),
- Magnets perfectly protect themselves against loss of magnetization caused by foreign field sources,
- By covering with a lustrous layer of silver, the element presents an aesthetic look,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- In view of the potential of flexible shaping and customization to unique requirements, neodymium magnets can be modeled in a wide range of shapes and sizes, which amplifies use scope,
- Versatile presence in high-tech industry – they are utilized in computer drives, motor assemblies, diagnostic systems, and technologically advanced constructions.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Limitations
- At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We suggest a housing - magnetic holder, due to difficulties in realizing threads inside the magnet and complicated shapes.
- Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Additionally, tiny parts of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- Due to expensive raw materials, their price is relatively high,
Pull force analysis
Highest magnetic holding force – what it depends on?
- on a base made of mild steel, effectively closing the magnetic field
- possessing a thickness of min. 10 mm to ensure full flux closure
- characterized by smoothness
- under conditions of ideal adhesion (metal-to-metal)
- during pulling in a direction perpendicular to the mounting surface
- at standard ambient temperature
Practical lifting capacity: influencing factors
- Air gap (between the magnet and the metal), since even a microscopic distance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, rust or dirt).
- Angle of force application – highest force is obtained only during perpendicular pulling. The shear force of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick plate does not close the flux, causing part of the power to be escaped into the air.
- Material type – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
- Temperature – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.
Warnings
Allergic reactions
It is widely known that nickel (the usual finish) is a common allergen. If you have an allergy, avoid touching magnets with bare hands and opt for encased magnets.
Threat to electronics
Very strong magnetic fields can erase data on payment cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Power loss in heat
Control the heat. Heating the magnet to high heat will permanently weaken its magnetic structure and pulling force.
Medical implants
Warning for patients: Strong magnetic fields affect electronics. Keep at least 30 cm distance or ask another person to work with the magnets.
Swallowing risk
Always store magnets away from children. Choking hazard is significant, and the effects of magnets clamping inside the body are very dangerous.
Crushing risk
Big blocks can break fingers in a fraction of a second. Never put your hand between two attracting surfaces.
GPS Danger
GPS units and mobile phones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can permanently damage the sensors in your phone.
Mechanical processing
Combustion risk: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.
Respect the power
Handle magnets consciously. Their huge power can surprise even professionals. Plan your moves and respect their power.
Material brittleness
Neodymium magnets are ceramic materials, which means they are fragile like glass. Impact of two magnets leads to them breaking into shards.
