Advantages as well as disadvantages of neodymium magnets.
Benefits
- They retain magnetic properties for almost ten years – the loss is just ~1% (in theory),
- They do not lose their magnetic properties even under external field action,
- The use of an refined finish of noble metals (nickel, gold, silver) causes the element to look better,
- The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
- 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 designing and the ability to adapt to client solutions,
- Wide application in future technologies – they are commonly used in computer drives, brushless drives, medical devices, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in miniature devices
Weaknesses
- At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can lose 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 suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- We suggest cover - magnetic mount, due to difficulties in producing nuts inside the magnet and complex forms.
- Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that small elements of these products are able to complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum lifting force for a neodymium magnet – what affects it?
- with the application of a sheet made of special test steel, guaranteeing full magnetic saturation
- with a cross-section of at least 10 mm
- with a plane cleaned and smooth
- with direct contact (without impurities)
- during pulling in a direction perpendicular to the plane
- in neutral thermal conditions
Practical aspects of lifting capacity – factors
- Distance (betwixt the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Steel grade – ideal substrate is high-permeability steel. Cast iron may attract less.
- Base smoothness – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the holding force is lower. Moreover, even a small distance between the magnet and the plate lowers the holding force.
Safe handling of NdFeB magnets
Implant safety
Warning for patients: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
Warning for allergy sufferers
Certain individuals suffer from a hypersensitivity to nickel, which is the standard coating for NdFeB magnets. Extended handling may cause a rash. We strongly advise wear protective gloves.
Choking Hazard
These products are not suitable for play. Swallowing several magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and requires immediate surgery.
Powerful field
Use magnets with awareness. Their huge power can shock even experienced users. Plan your moves and respect their power.
Mechanical processing
Mechanical processing of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Risk of cracking
Protect your eyes. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
Safe distance
Equipment safety: Strong magnets can damage payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
Crushing force
Large magnets can smash fingers instantly. Under no circumstances place your hand between two attracting surfaces.
Impact on smartphones
Be aware: rare earth magnets produce a field that confuses sensitive sensors. Maintain a separation from your mobile, device, and GPS.
Heat sensitivity
Watch the temperature. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
