Strengths as well as weaknesses of neodymium magnets.
Advantages
- They do not lose magnetism, even over approximately ten years – the reduction in power is only ~1% (based on measurements),
- Magnets effectively protect themselves against loss of magnetization caused by ambient magnetic noise,
- The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnetic induction on the surface of the magnet remains extremely intense,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- In view of the option of flexible forming and customization to unique projects, neodymium magnets can be modeled in a variety of forms and dimensions, which expands the range of possible applications,
- Universal use in electronics industry – they serve a role in hard drives, electromotive mechanisms, medical devices, also technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Cons
- To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability 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 secure oxidation as well as corrosion.
- Due to limitations in creating nuts and complex shapes in magnets, we propose using casing - magnetic holder.
- Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, small elements of these devices are able to complicate diagnosis medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is economically unviable,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what it depends on?
- on a block made of mild steel, perfectly concentrating the magnetic field
- possessing a massiveness of at least 10 mm to avoid saturation
- characterized by lack of roughness
- with zero gap (no paint)
- during detachment in a direction vertical to the mounting surface
- at standard ambient temperature
Practical aspects of lifting capacity – factors
- Space between magnet and steel – 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.
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Base massiveness – insufficiently thick sheet causes magnetic saturation, causing part of the flux to be wasted to the other side.
- Material composition – not every steel attracts identically. Alloy additives weaken the attraction effect.
- Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Temperature influence – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet and the plate decreases the holding force.
Warnings
Crushing risk
Large magnets can smash fingers instantly. Do not place your hand betwixt two attracting surfaces.
This is not a toy
Always keep magnets out of reach of children. Ingestion danger is high, and the consequences of magnets connecting inside the body are fatal.
Thermal limits
Control the heat. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.
Compass and GPS
Navigation devices and mobile phones are highly susceptible to magnetic fields. Close proximity with a strong magnet can ruin the sensors in your phone.
Medical interference
People with a pacemaker have to maintain an large gap from magnets. The magnetic field can stop the operation of the implant.
Skin irritation risks
A percentage of the population suffer from a hypersensitivity to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching can result in skin redness. We suggest wear safety gloves.
Magnetic media
Avoid bringing magnets close to a purse, computer, or TV. The magnetism can destroy these devices and erase data from cards.
Respect the power
Use magnets consciously. Their powerful strength can surprise even professionals. Plan your moves and do not underestimate their force.
Fragile material
NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Impact of two magnets will cause them breaking into small pieces.
Combustion hazard
Mechanical processing of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
