Pros as well as cons of neodymium magnets.
Pros
- They retain full power for nearly 10 years – the drop is just ~1% (in theory),
- They feature excellent resistance to weakening of magnetic properties when exposed to opposing magnetic fields,
- Thanks to the elegant finish, the surface of Ni-Cu-Ni, gold, or silver-plated gives an professional appearance,
- Magnets possess maximum magnetic induction on the surface,
- 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 potential of accurate shaping and customization to individualized solutions, neodymium magnets can be produced in a wide range of forms and dimensions, which amplifies use scope,
- Wide application in electronics industry – they are utilized in magnetic memories, brushless drives, medical equipment, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in miniature devices
Limitations
- At very strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We suggest a housing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Health risk to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. Furthermore, small components of these devices can complicate diagnosis medical after entering the body.
- Due to complex production process, their price is higher than average,
Lifting parameters
Highest magnetic holding force – what it depends on?
- with the use of a sheet made of special test steel, ensuring maximum field concentration
- with a thickness of at least 10 mm
- with a surface cleaned and smooth
- with direct contact (without impurities)
- during detachment in a direction perpendicular to the plane
- in neutral thermal conditions
Key elements affecting lifting force
- Gap (betwixt the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, rust or debris).
- Direction of force – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Metal type – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, however under shearing force the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate reduces the load capacity.
H&S for magnets
Maximum temperature
Regular neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. This process is irreversible.
Machining danger
Fire warning: Neodymium dust is highly flammable. Do not process magnets without safety gear as this may cause fire.
No play value
Only for adults. Tiny parts pose a choking risk, leading to severe trauma. Keep out of reach of children and animals.
Warning for heart patients
Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Serious injuries
Large magnets can break fingers instantly. Under no circumstances place your hand betwixt two attracting surfaces.
Skin irritation risks
Certain individuals experience a sensitization to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact might lead to a rash. We recommend use safety gloves.
Precision electronics
A strong magnetic field negatively affects the operation of compasses in smartphones and GPS navigation. Maintain magnets close to a device to avoid breaking the sensors.
Electronic devices
Avoid bringing magnets close to a wallet, laptop, or screen. The magnetism can permanently damage these devices and wipe information from cards.
Risk of cracking
Neodymium magnets are ceramic materials, which means they are fragile like glass. Clashing of two magnets will cause them breaking into small pieces.
Respect the power
Use magnets with awareness. Their immense force can surprise even professionals. Be vigilant and do not underestimate their force.
