Strengths and weaknesses of Nd2Fe14B magnets.
Benefits
- Their strength is durable, and after around ten years it drops only by ~1% (theoretically),
- Neodymium magnets are remarkably resistant to demagnetization caused by external field sources,
- In other words, due to the metallic layer of silver, the element becomes visually attractive,
- Neodymium magnets create maximum magnetic induction on a small surface, which ensures high operational effectiveness,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Possibility of detailed creating as well as modifying to individual requirements,
- Universal use in electronics industry – they are utilized in data components, motor assemblies, precision medical tools, as well as multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Limitations
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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 extremely resistant to heat
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing nuts and complicated forms in magnets, we recommend using a housing - magnetic holder.
- Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these magnets can be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Magnetic strength at its maximum – what affects it?
- with the application of a yoke made of special test steel, guaranteeing maximum field concentration
- whose transverse dimension reaches at least 10 mm
- characterized by lack of roughness
- with total lack of distance (no impurities)
- during pulling in a direction perpendicular to the plane
- at standard ambient temperature
Lifting capacity in practice – influencing factors
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Load vector – highest force is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Metal type – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
- Smoothness – ideal contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was measured with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Bone fractures
Mind your fingers. Two large magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Avoid contact if allergic
Medical facts indicate that nickel (standard magnet coating) is a potent allergen. If you have an allergy, avoid touching magnets with bare hands and choose coated magnets.
Impact on smartphones
A strong magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Keep magnets near a device to avoid damaging the sensors.
Heat warning
Control the heat. Heating the magnet to high heat will permanently weaken its properties and pulling force.
Conscious usage
Be careful. Neodymium magnets act from a distance and connect with huge force, often faster than you can react.
Danger to pacemakers
Individuals with a heart stimulator must keep an absolute distance from magnets. The magnetism can interfere with the functioning of the implant.
Data carriers
Avoid bringing magnets near a purse, laptop, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
Risk of cracking
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.
Adults only
Product intended for adults. Small elements pose a choking risk, causing severe trauma. Keep away from kids and pets.
Dust is flammable
Combustion risk: Rare earth powder is highly flammable. Do not process magnets in home conditions as this may cause fire.
