Pros as well as cons of Nd2Fe14B magnets.
Pros
- Their magnetic field remains stable, and after around ten years it drops only by ~1% (according to research),
- They maintain their magnetic properties even under strong external field,
- The use of an refined coating of noble metals (nickel, gold, silver) causes the element to look better,
- Magnets have exceptionally strong magnetic induction on the outer layer,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to freedom in constructing and the capacity to adapt to individual projects,
- Versatile presence in modern technologies – they serve a role in mass storage devices, electromotive mechanisms, medical devices, also multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Limitations
- At very strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Due to limitations in creating threads and complicated shapes in magnets, we recommend using casing - magnetic mechanism.
- Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. Furthermore, tiny parts of these products can disrupt the diagnostic process medical when they are in the body.
- Due to neodymium price, their price exceeds standard values,
Pull force analysis
Maximum lifting capacity of the magnet – what affects it?
- with the contact of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- possessing a thickness of min. 10 mm to avoid saturation
- with a plane perfectly flat
- without any air gap between the magnet and steel
- under vertical application of breakaway force (90-degree angle)
- at room temperature
Determinants of lifting force in real conditions
- Clearance – the presence of foreign body (rust, dirt, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Steel thickness – insufficiently thick sheet does not close the flux, causing part of the flux to be escaped into the air.
- Plate material – mild steel gives the best results. Alloy steels lower magnetic properties and lifting capacity.
- Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature influence – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a slight gap between the magnet and the plate lowers the lifting capacity.
H&S for magnets
Immense force
Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Dust explosion hazard
Fire warning: Neodymium dust is highly flammable. Do not process magnets in home conditions as this may cause fire.
Avoid contact if allergic
Medical facts indicate that the nickel plating (the usual finish) is a potent allergen. For allergy sufferers, avoid touching magnets with bare hands or choose coated magnets.
Magnet fragility
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Impact on smartphones
GPS units and smartphones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Physical harm
Big blocks can crush fingers instantly. Do not place your hand between two strong magnets.
Health Danger
Life threat: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
Protect data
Powerful magnetic fields can erase data on credit cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Permanent damage
Keep cool. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Product not for children
Absolutely store magnets away from children. Risk of swallowing is high, and the effects of magnets connecting inside the body are life-threatening.
