Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- They do not lose magnetism, even after nearly ten years – the drop in power is only ~1% (based on measurements),
- Neodymium magnets are characterized by exceptionally resistant to loss of magnetic properties caused by external magnetic fields,
- By applying a shiny layer of silver, the element presents an professional look,
- Magnets have impressive magnetic induction on the active area,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures reaching 230°C and above...
- In view of the potential of accurate molding and adaptation to unique needs, NdFeB magnets can be manufactured in a wide range of shapes and sizes, which increases their versatility,
- Universal use in high-tech industry – they are utilized in HDD drives, electric motors, medical equipment, also complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- 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 rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic mount, due to difficulties in producing threads inside the magnet and complicated shapes.
- Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that tiny parts of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what affects it?
- using a base made of low-carbon steel, acting as a magnetic yoke
- whose thickness reaches at least 10 mm
- with an ideally smooth touching surface
- without the slightest clearance between the magnet and steel
- during detachment in a direction perpendicular to the mounting surface
- at standard ambient temperature
Magnet lifting force in use – key factors
- Space between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Steel grade – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
- Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
- Thermal environment – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under a perpendicular pulling force, however under parallel forces the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Safe handling of neodymium magnets
Flammability
Fire warning: Neodymium dust is explosive. Avoid machining magnets in home conditions as this may cause fire.
Handling guide
Handle with care. Neodymium magnets act from a distance and connect with massive power, often faster than you can move away.
Heat warning
Standard neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.
Precision electronics
GPS units and mobile phones are extremely susceptible to magnetism. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Protect data
Equipment safety: Strong magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).
Hand protection
Risk of injury: The pulling power is so immense that it can result in blood blisters, pinching, and broken bones. Use thick gloves.
Keep away from children
Strictly store magnets out of reach of children. Choking hazard is significant, and the consequences of magnets connecting inside the body are tragic.
Allergic reactions
It is widely known that nickel (the usual finish) is a potent allergen. If your skin reacts to metals, avoid touching magnets with bare hands or choose versions in plastic housing.
Beware of splinters
Protect your eyes. Magnets can fracture upon violent connection, launching sharp fragments into the air. Wear goggles.
Medical implants
Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
