Pros as well as cons of neodymium magnets.
Pros
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- They possess excellent resistance to magnetism drop due to external magnetic sources,
- A magnet with a smooth gold surface has an effective appearance,
- They feature high magnetic induction at the operating surface, which increases their power,
- 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 modularity in shaping and the ability to adapt to individual projects,
- Significant place in electronics industry – they are used in computer drives, electric drive systems, precision medical tools, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in miniature devices
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- 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.
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing threads and complicated shapes in magnets, we recommend using a housing - magnetic mount.
- Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these products can be problematic in diagnostics medical when they are in the body.
- With budget limitations the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum lifting capacity of the magnet – what contributes to it?
- on a base made of structural steel, effectively closing the magnetic field
- whose transverse dimension reaches at least 10 mm
- with a surface cleaned and smooth
- with direct contact (without paint)
- under vertical application of breakaway force (90-degree angle)
- in stable room temperature
Lifting capacity in practice – influencing factors
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Steel grade – ideal substrate is high-permeability steel. Hardened steels may attract less.
- Surface structure – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under shearing force the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate reduces the holding force.
Eye protection
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
Pacemakers
Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Magnetic interference
GPS units and mobile phones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Flammability
Machining of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Threat to electronics
Avoid bringing magnets close to a purse, computer, or TV. The magnetic field can permanently damage these devices and erase data from cards.
Product not for children
NdFeB magnets are not suitable for play. Eating multiple magnets may result in them attracting across intestines, which constitutes a critical condition and necessitates immediate surgery.
Power loss in heat
Control the heat. Heating the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Hand protection
Pinching hazard: The attraction force is so great that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.
Allergy Warning
It is widely known that nickel (standard magnet coating) is a common allergen. If you have an allergy, prevent touching magnets with bare hands or opt for coated magnets.
Handling rules
Exercise caution. Rare earth magnets attract from a distance and connect with huge force, often faster than you can move away.
