Pros and cons of Nd2Fe14B magnets.
Benefits
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (according to literature),
- They do not lose their magnetic properties even under external field action,
- A magnet with a smooth gold surface has better aesthetics,
- The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Thanks to the potential of precise forming and adaptation to custom needs, magnetic components can be modeled in a variety of geometric configurations, which increases their versatility,
- Wide application in modern technologies – they are commonly used in mass storage devices, electric drive systems, advanced medical instruments, and industrial machines.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- We suggest cover - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that small components of these products are able to disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Maximum lifting force for a neodymium magnet – what contributes to it?
- on a block made of mild steel, optimally conducting the magnetic flux
- possessing a massiveness of at least 10 mm to avoid saturation
- with a surface perfectly flat
- with direct contact (without impurities)
- under perpendicular force direction (90-degree angle)
- at ambient temperature room level
Impact of factors on magnetic holding capacity in practice
- Air gap (between the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Material composition – not every steel reacts the same. Alloy additives worsen the interaction with the magnet.
- Surface finish – full contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Eye protection
Despite the nickel coating, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
Magnetic media
Intense magnetic fields can destroy records on credit cards, hard drives, and storage devices. Stay away of at least 10 cm.
Allergy Warning
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, cease working with magnets and wear gloves.
Crushing risk
Risk of injury: The pulling power is so great that it can result in hematomas, pinching, and even bone fractures. Protective gloves are recommended.
No play value
Always keep magnets out of reach of children. Choking hazard is significant, and the effects of magnets clamping inside the body are fatal.
Precision electronics
Navigation devices and mobile phones are extremely sensitive to magnetism. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.
Warning for heart patients
Warning for patients: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.
Dust explosion hazard
Dust created during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Conscious usage
Before starting, read the rules. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Power loss in heat
Avoid heat. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).
