Pros as well as cons of neodymium magnets.
Benefits
- They retain full power for around ten years – the drop is just ~1% (based on simulations),
- They have excellent resistance to weakening of magnetic properties due to external magnetic sources,
- In other words, due to the aesthetic layer of gold, the element gains visual value,
- Magnetic induction on the top side of the magnet turns out to be very high,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
- In view of the possibility of flexible molding and adaptation to specialized solutions, magnetic components can be modeled in a broad palette of geometric configurations, which amplifies use scope,
- Wide application in high-tech industry – they serve a role in hard drives, electric motors, advanced medical instruments, as well as industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- At very strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We recommend casing - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated forms.
- Potential hazard resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Additionally, small components of these products can complicate diagnosis medical after entering the body.
- With mass production the cost of neodymium magnets can be a barrier,
Holding force characteristics
Magnetic strength at its maximum – what contributes to it?
- on a plate made of mild steel, perfectly concentrating the magnetic flux
- whose transverse dimension reaches at least 10 mm
- with a plane cleaned and smooth
- with total lack of distance (no impurities)
- for force applied at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Determinants of practical lifting force of a magnet
- Distance (between the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Material composition – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
- Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Thermal environment – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet and the plate lowers the load capacity.
Safe handling of NdFeB magnets
Crushing risk
Big blocks can break fingers in a fraction of a second. Under no circumstances put your hand betwixt two strong magnets.
Protect data
Avoid bringing magnets close to a wallet, laptop, or TV. The magnetism can permanently damage these devices and erase data from cards.
Handling guide
Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
Phone sensors
GPS units and smartphones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Risk of cracking
Despite the nickel coating, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Heat warning
Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Warning for allergy sufferers
It is widely known that the nickel plating (the usual finish) is a potent allergen. If your skin reacts to metals, avoid touching magnets with bare hands and choose versions in plastic housing.
Danger to pacemakers
For implant holders: Strong magnetic fields affect electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.
Fire risk
Machining of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Product not for children
Absolutely store magnets away from children. Choking hazard is high, and the consequences of magnets connecting inside the body are fatal.
