Strengths and weaknesses of neodymium magnets.
Advantages
- They do not lose magnetism, even during approximately 10 years – the decrease in strength is only ~1% (theoretically),
- Neodymium magnets are remarkably resistant to demagnetization caused by external field sources,
- By covering with a smooth coating of gold, the element acquires an proper look,
- Magnets are characterized by huge magnetic induction on the working surface,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of individual forming and adjusting to concrete requirements,
- Versatile presence in modern industrial fields – they are utilized in hard drives, electromotive mechanisms, advanced medical instruments, also technologically advanced constructions.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a steel housing, 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 drop of power (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 very resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Limited possibility of producing threads in the magnet and complex shapes - recommended is cover - mounting mechanism.
- Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Furthermore, small components of these products are able to complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum magnetic pulling force – what affects it?
- with the contact of a yoke made of special test steel, guaranteeing maximum field concentration
- with a thickness minimum 10 mm
- characterized by lack of roughness
- without the slightest insulating layer between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at ambient temperature room level
Key elements affecting lifting force
- Air gap (betwixt the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Plate material – mild steel attracts best. Alloy admixtures decrease magnetic properties and holding force.
- Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.
H&S for magnets
Magnet fragility
Neodymium magnets are ceramic materials, meaning they are prone to chipping. Impact of two magnets will cause them breaking into small pieces.
Finger safety
Large magnets can break fingers instantly. Never put your hand betwixt two strong magnets.
Machining danger
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Warning for allergy sufferers
Nickel alert: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, immediately stop handling magnets and wear gloves.
Threat to electronics
Avoid bringing magnets close to a wallet, computer, or screen. The magnetic field can destroy these devices and wipe information from cards.
Keep away from electronics
An intense magnetic field interferes with the operation of compasses in phones and navigation systems. Keep magnets close to a device to avoid damaging the sensors.
Conscious usage
Handle with care. Neodymium magnets act from a long distance and snap with huge force, often faster than you can react.
Maximum temperature
Standard neodymium magnets (N-type) lose power when the temperature surpasses 80°C. The loss of strength is permanent.
Medical interference
Patients with a heart stimulator should keep an large gap from magnets. The magnetism can interfere with the operation of the life-saving device.
Adults only
Neodymium magnets are not intended for children. Swallowing several magnets can lead to them connecting inside the digestive tract, which poses a severe health hazard and necessitates urgent medical intervention.
