Pros as well as cons of Nd2Fe14B magnets.
Pros
- They have constant strength, and over around 10 years their attraction force decreases symbolically – ~1% (in testing),
- They are extremely resistant to demagnetization induced by presence of other magnetic fields,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to look better,
- Magnets exhibit excellent magnetic induction on the outer side,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to freedom in designing and the capacity to customize to individual projects,
- Wide application in innovative solutions – they are utilized in computer drives, electromotive mechanisms, medical devices, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in small systems
Cons
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in producing threads and complicated shapes in magnets, we propose using casing - magnetic mount.
- Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Additionally, tiny parts of these products can complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Maximum holding power of the magnet – what affects it?
- with the use of a yoke made of low-carbon steel, ensuring maximum field concentration
- whose transverse dimension is min. 10 mm
- with an polished contact surface
- without any insulating layer between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Determinants of lifting force in real conditions
- Distance – existence of any layer (paint, tape, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds much less (often approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Plate material – mild steel gives the best results. Alloy steels reduce magnetic properties and holding force.
- Surface condition – smooth surfaces ensure maximum contact, which improves force. Rough surfaces weaken the grip.
- Temperature influence – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was assessed with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the lifting capacity is smaller. In addition, even a small distance between the magnet and the plate reduces the holding force.
Warnings
GPS and phone interference
Navigation devices and smartphones are extremely susceptible to magnetism. Close proximity with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Powerful field
Exercise caution. Rare earth magnets attract from a long distance and snap with massive power, often faster than you can react.
Cards and drives
Powerful magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.
Sensitization to coating
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness happens, immediately stop working with magnets and use protective gear.
Finger safety
Big blocks can smash fingers in a fraction of a second. Under no circumstances put your hand between two strong magnets.
Operating temperature
Standard neodymium magnets (grade N) lose power when the temperature goes above 80°C. Damage is permanent.
Medical implants
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Combustion hazard
Fire hazard: Rare earth powder is explosive. Do not process magnets in home conditions as this may cause fire.
Beware of splinters
Beware of splinters. Magnets can explode upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.
Danger to the youngest
NdFeB magnets are not suitable for play. Eating several magnets may result in them pinching intestinal walls, which poses a severe health hazard and necessitates urgent medical intervention.
