Pros as well as cons of Nd2Fe14B magnets.
Advantages
- They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (according to literature),
- They feature excellent resistance to magnetic field loss due to external fields,
- In other words, due to the smooth layer of silver, the element becomes visually attractive,
- The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Thanks to the option of free shaping and adaptation to individualized projects, NdFeB magnets can be produced in a broad palette of forms and dimensions, which amplifies use scope,
- Versatile presence in electronics industry – they serve a role in mass storage devices, motor assemblies, medical equipment, and other advanced devices.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Weaknesses
- To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as 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 resistant to moisture, when using outdoors
- Limited ability of creating threads in the magnet and complicated forms - preferred is a housing - magnet mounting.
- Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these magnets are able to complicate diagnosis medical when they are in the body.
- Due to complex production process, their price is relatively high,
Pull force analysis
Best holding force of the magnet in ideal parameters – what contributes to it?
- with the contact of a sheet made of low-carbon steel, ensuring maximum field concentration
- whose thickness reaches at least 10 mm
- with a surface free of scratches
- with direct contact (no impurities)
- during pulling in a direction vertical to the mounting surface
- at temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Gap between surfaces – every millimeter of distance (caused e.g. by varnish or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Direction of force – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Chemical composition of the base – mild steel gives the best results. Alloy steels reduce magnetic properties and holding force.
- Plate texture – ground elements ensure maximum contact, which improves force. Uneven metal reduce efficiency.
- Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Safety rules for work with NdFeB magnets
Heat sensitivity
Avoid heat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
Magnet fragility
Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.
Data carriers
Do not bring magnets near a purse, laptop, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Fire warning
Drilling and cutting of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Caution required
Before use, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Bone fractures
Watch your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Do not give to children
Product intended for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Store away from kids and pets.
Compass and GPS
Note: neodymium magnets generate a field that interferes with precision electronics. Keep a safe distance from your mobile, tablet, and navigation systems.
Allergic reactions
Medical facts indicate that the nickel plating (the usual finish) is a potent allergen. For allergy sufferers, refrain from direct skin contact or opt for coated magnets.
Medical interference
Medical warning: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
