Pros as well as cons of Nd2Fe14B magnets.
Pros
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (based on calculations),
- Neodymium magnets prove to be remarkably resistant to demagnetization caused by external field sources,
- A magnet with a shiny gold surface is more attractive,
- The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to modularity in forming and the ability to modify to specific needs,
- Significant place in innovative solutions – they are used in HDD drives, drive modules, medical devices, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in compact constructions
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also increases 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.
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We suggest a housing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex forms.
- Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these products are able to complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what affects it?
- using a base made of high-permeability steel, functioning as a ideal flux conductor
- whose thickness is min. 10 mm
- with a surface cleaned and smooth
- under conditions of ideal adhesion (metal-to-metal)
- under perpendicular application of breakaway force (90-degree angle)
- at conditions approx. 20°C
Key elements affecting lifting force
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Direction of force – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin sheet causes magnetic saturation, causing part of the flux to be wasted to the other side.
- Chemical composition of the base – mild steel attracts best. Alloy steels reduce magnetic permeability and lifting capacity.
- Surface structure – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Thermal environment – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a small distance between the magnet and the plate decreases the holding force.
Warnings
Heat warning
Regular neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.
Keep away from electronics
Navigation devices and mobile phones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
Fire warning
Combustion risk: Rare earth powder is highly flammable. Do not process magnets in home conditions as this risks ignition.
Adults only
Always keep magnets away from children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are life-threatening.
Beware of splinters
Beware of splinters. Magnets can fracture upon violent connection, launching shards into the air. Wear goggles.
Avoid contact if allergic
Certain individuals experience a sensitization to Ni, which is the standard coating for neodymium magnets. Extended handling may cause an allergic reaction. We recommend wear protective gloves.
Pacemakers
Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
Serious injuries
Large magnets can crush fingers instantly. Never put your hand between two attracting surfaces.
Threat to electronics
Do not bring magnets near a wallet, laptop, or TV. The magnetism can destroy these devices and wipe information from cards.
Respect the power
Handle with care. Neodymium magnets act from a long distance and connect with massive power, often quicker than you can react.
