Pros and cons of Nd2Fe14B magnets.
Strengths
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- Neodymium magnets remain highly resistant to magnetic field loss caused by external interference,
- A magnet with a metallic silver surface has an effective appearance,
- They feature high magnetic induction at the operating surface, which increases their power,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of precise modeling and adapting to precise requirements,
- Significant place in innovative solutions – they find application in computer drives, drive modules, advanced medical instruments, also industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in small systems
Cons
- To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of creating threads in the magnet and complicated forms - recommended is a housing - magnet mounting.
- Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these devices can complicate diagnosis medical in case of swallowing.
- Due to complex production process, their price is higher than average,
Lifting parameters
Maximum lifting capacity of the magnet – what contributes to it?
- on a base made of structural steel, effectively closing the magnetic field
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with a plane cleaned and smooth
- without any air gap between the magnet and steel
- during detachment in a direction vertical to the mounting surface
- at room temperature
What influences lifting capacity in practice
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Base massiveness – insufficiently thick sheet does not accept the full field, causing part of the power to be lost to the other side.
- Steel grade – the best choice is pure iron steel. Hardened steels may attract less.
- Base smoothness – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
- Temperature – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under shearing force the holding force is lower. Moreover, even a slight gap between the magnet and the plate decreases the load capacity.
Precautions when working with neodymium magnets
Health Danger
Life threat: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Combustion hazard
Drilling and cutting of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Immense force
Handle with care. Neodymium magnets attract from a distance and snap with huge force, often faster than you can react.
Threat to electronics
Equipment safety: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, medical aids, timepieces).
Eye protection
Neodymium magnets are ceramic materials, meaning they are prone to chipping. Collision of two magnets leads to them breaking into shards.
Sensitization to coating
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If redness occurs, cease handling magnets and use protective gear.
Threat to navigation
A powerful magnetic field interferes with the functioning of compasses in phones and GPS navigation. Maintain magnets near a device to avoid damaging the sensors.
Crushing force
Mind your fingers. Two powerful magnets will join immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Permanent damage
Control the heat. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.
This is not a toy
These products are not suitable for play. Eating multiple magnets may result in them attracting across intestines, which poses a direct threat to life and necessitates immediate surgery.
