Pros as well as cons of Nd2Fe14B magnets.
Pros
- They do not lose power, even over around ten years – the reduction in strength is only ~1% (theoretically),
- They feature excellent resistance to weakening of magnetic properties due to opposing magnetic fields,
- A magnet with a metallic gold surface looks better,
- Magnets have very high magnetic induction on the surface,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to freedom in shaping and the capacity to modify to individual projects,
- Significant place in modern technologies – they find application in data components, electromotive mechanisms, precision medical tools, as well as technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in miniature devices
Limitations
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited ability of creating threads in the magnet and complex shapes - recommended is a housing - magnet mounting.
- Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these products are able to be problematic in diagnostics medical when they are in the body.
- With large orders the cost of neodymium magnets is economically unviable,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what contributes to it?
- using a plate made of high-permeability steel, serving as a magnetic yoke
- with a cross-section minimum 10 mm
- characterized by lack of roughness
- without any air gap between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature room level
Determinants of lifting force in real conditions
- Gap (betwixt the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Plate material – low-carbon steel attracts best. Higher carbon content reduce magnetic permeability and holding force.
- Surface structure – the more even the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal factor – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate decreases the load capacity.
Warnings
Dust is flammable
Fire hazard: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.
Impact on smartphones
Be aware: neodymium magnets generate a field that disrupts precision electronics. Maintain a safe distance from your phone, tablet, and GPS.
Swallowing risk
Strictly store magnets out of reach of children. Choking hazard is high, and the effects of magnets connecting inside the body are tragic.
Protective goggles
Despite metallic appearance, the material is brittle and not impact-resistant. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Handling guide
Handle with care. Neodymium magnets attract from a distance and snap with massive power, often quicker than you can move away.
Pacemakers
For implant holders: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.
Bodily injuries
Risk of injury: The pulling power is so great that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
Avoid contact if allergic
It is widely known that nickel (standard magnet coating) is a potent allergen. If your skin reacts to metals, prevent direct skin contact or choose coated magnets.
Threat to electronics
Equipment safety: Neodymium magnets can ruin data carriers and sensitive devices (heart implants, medical aids, timepieces).
Power loss in heat
Regular neodymium magnets (N-type) lose power when the temperature exceeds 80°C. This process is irreversible.
