Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- Their strength is maintained, and after approximately ten years it decreases only by ~1% (theoretically),
- Neodymium magnets are distinguished by remarkably resistant to loss of magnetic properties caused by external interference,
- By applying a shiny coating of nickel, the element presents an aesthetic look,
- Neodymium magnets achieve maximum magnetic induction on a their surface, which increases force concentration,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures approaching 230°C and above...
- Considering the option of flexible forming and customization to unique needs, magnetic components can be modeled in a variety of shapes and sizes, which makes them more universal,
- Versatile presence in innovative solutions – they find application in magnetic memories, electric motors, medical devices, also industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which enables their usage in compact constructions
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (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
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We suggest cover - magnetic mount, due to difficulties in producing threads inside the magnet and complex forms.
- Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products can disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Maximum magnetic pulling force – what it depends on?
- on a base made of mild steel, perfectly concentrating the magnetic flux
- whose thickness equals approx. 10 mm
- characterized by even structure
- under conditions of ideal adhesion (metal-to-metal)
- under vertical force direction (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in real conditions – factors
- Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Direction of force – maximum parameter is reached only during pulling at a 90° angle. The force required to slide of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Material type – ideal substrate is pure iron steel. Stainless steels may have worse magnetic properties.
- Surface quality – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Thermal environment – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, however under parallel forces the holding force is lower. Additionally, even a small distance between the magnet and the plate decreases the holding force.
Warnings
Crushing risk
Big blocks can smash fingers instantly. Under no circumstances place your hand between two strong magnets.
Heat sensitivity
Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. This process is irreversible.
Conscious usage
Handle magnets with awareness. Their huge power can surprise even professionals. Plan your moves and do not underestimate their power.
Data carriers
Device Safety: Strong magnets can damage data carriers and sensitive devices (pacemakers, hearing aids, mechanical watches).
Machining danger
Dust generated during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Avoid contact if allergic
Nickel alert: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, cease handling magnets and use protective gear.
This is not a toy
NdFeB magnets are not suitable for play. Swallowing several magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and necessitates immediate surgery.
Warning for heart patients
Life threat: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Risk of cracking
Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Precision electronics
Remember: rare earth magnets produce a field that confuses precision electronics. Keep a safe distance from your mobile, tablet, and navigation systems.
