Advantages as well as disadvantages of Nd2Fe14B magnets.
Advantages
- They retain magnetic properties for almost 10 years – the drop is just ~1% (based on simulations),
- Magnets effectively defend themselves against demagnetization caused by foreign field sources,
- By using a smooth coating of nickel, the element gains an professional look,
- Magnets possess very high magnetic induction on the active area,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of precise shaping and adjusting to atypical conditions,
- Key role in electronics industry – they are utilized in computer drives, drive modules, medical devices, also modern systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Disadvantages
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only secures them against impacts but also raises their durability
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited ability of creating nuts in the magnet and complex shapes - preferred is cover - magnetic holder.
- Possible danger to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small elements of these devices can complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Maximum lifting capacity of the magnet – what it depends on?
- with the contact of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- possessing a massiveness of at least 10 mm to avoid saturation
- characterized by lack of roughness
- without the slightest air gap between the magnet and steel
- during detachment in a direction vertical to the plane
- at room temperature
Lifting capacity in real conditions – factors
- Distance – the presence of foreign body (paint, tape, air) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is reached only during perpendicular pulling. The resistance to sliding of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Metal type – different alloys reacts the same. Alloy additives worsen the interaction with the magnet.
- Base smoothness – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
- Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
Pacemakers
Warning for patients: Powerful magnets affect electronics. Maintain minimum 30 cm distance or ask another person to work with the magnets.
Electronic hazard
Powerful magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.
Risk of cracking
Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.
Conscious usage
Before use, check safety instructions. Sudden snapping can break the magnet or injure your hand. Be predictive.
Impact on smartphones
Note: neodymium magnets generate a field that disrupts precision electronics. Maintain a separation from your mobile, tablet, and navigation systems.
Machining danger
Powder created during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Power loss in heat
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its properties and pulling force.
Bone fractures
Protect your hands. Two large magnets will join immediately with a force of several hundred kilograms, destroying anything in their path. Be careful!
Avoid contact if allergic
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness appears, cease handling magnets and wear gloves.
Keep away from children
Always store magnets away from children. Ingestion danger is high, and the effects of magnets connecting inside the body are fatal.
