Pros as well as cons of neodymium magnets.
Pros
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
- They possess excellent resistance to magnetism drop due to opposing magnetic fields,
- Thanks to the metallic finish, the coating of Ni-Cu-Ni, gold-plated, or silver-plated gives an aesthetic appearance,
- Magnetic induction on the working layer of the magnet remains strong,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures approaching 230°C and above...
- Thanks to modularity in designing and the ability to customize to specific needs,
- Fundamental importance in future technologies – they serve a role in HDD drives, drive modules, medical equipment, also technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- Neodymium magnets lose their force 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
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
- Due to limitations in realizing threads and complex shapes in magnets, we propose using a housing - magnetic holder.
- Health risk to health – tiny shards 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 products are able to be problematic in diagnostics medical after entering the body.
- With mass production the cost of neodymium magnets is a challenge,
Lifting parameters
Best holding force of the magnet in ideal parameters – what contributes to it?
- using a base made of mild steel, serving as a circuit closing element
- whose thickness reaches at least 10 mm
- with a surface cleaned and smooth
- with total lack of distance (no coatings)
- for force acting at a right angle (pull-off, not shear)
- at standard ambient temperature
Practical lifting capacity: influencing factors
- Gap (between the magnet and the plate), as even a very small distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Load vector – maximum parameter is reached only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Steel grade – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
- Surface condition – ground elements ensure maximum contact, which improves field saturation. Uneven metal reduce efficiency.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. Moreover, even a slight gap between the magnet and the plate reduces the lifting capacity.
H&S for magnets
Danger to the youngest
Always keep magnets out of reach of children. Ingestion danger is high, and the consequences of magnets connecting inside the body are fatal.
Safe operation
Exercise caution. Rare earth magnets attract from a long distance and connect with massive power, often faster than you can react.
Danger to pacemakers
Life threat: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Allergy Warning
A percentage of the population suffer from a sensitization to nickel, which is the common plating for neodymium magnets. Frequent touching can result in skin redness. We suggest wear safety gloves.
Keep away from computers
Avoid bringing magnets near a wallet, computer, or screen. The magnetic field can destroy these devices and wipe information from cards.
Mechanical processing
Fire hazard: Neodymium dust is highly flammable. Do not process magnets in home conditions as this may cause fire.
Magnetic interference
GPS units and mobile phones are extremely susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Operating temperature
Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. This process is irreversible.
Bodily injuries
Danger of trauma: The pulling power is so immense that it can cause blood blisters, crushing, and broken bones. Use thick gloves.
Fragile material
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Impact of two magnets will cause them cracking into shards.
