Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- They do not lose magnetism, even over around 10 years – the decrease in lifting capacity is only ~1% (based on measurements),
- They have excellent resistance to magnetic field loss as a result of external magnetic sources,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnets have extremely high magnetic induction on the active area,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of precise forming and adapting to specific needs,
- Wide application in advanced technology sectors – they are commonly used in magnetic memories, brushless drives, medical devices, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in compact constructions
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects 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.
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Limited ability of producing threads in the magnet and complicated forms - recommended is a housing - magnet mounting.
- Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these products are able to disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what it depends on?
- on a plate made of structural steel, optimally conducting the magnetic flux
- whose thickness equals approx. 10 mm
- characterized by smoothness
- with zero gap (no coatings)
- under vertical force direction (90-degree angle)
- in temp. approx. 20°C
Lifting capacity in practice – influencing factors
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Plate thickness – insufficiently thick plate does not accept the full field, causing part of the power to be wasted into the air.
- Steel grade – ideal substrate is high-permeability steel. Stainless steels may attract less.
- Surface structure – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Temperature – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
Precautions when working with NdFeB magnets
Keep away from electronics
Remember: rare earth magnets generate a field that interferes with sensitive sensors. Maintain a safe distance from your phone, device, and navigation systems.
Electronic hazard
Equipment safety: Strong magnets can ruin data carriers and delicate electronics (heart implants, medical aids, mechanical watches).
Nickel allergy
A percentage of the population suffer from a sensitization to Ni, which is the typical protective layer for neodymium magnets. Frequent touching might lead to a rash. We strongly advise use protective gloves.
Safe operation
Use magnets with awareness. Their huge power can surprise even experienced users. Be vigilant and respect their force.
Danger to pacemakers
For implant holders: Powerful magnets affect electronics. Keep minimum 30 cm distance or request help to handle the magnets.
Adults only
Always store magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are tragic.
Thermal limits
Watch the temperature. Heating the magnet to high heat will ruin its properties and pulling force.
Protective goggles
Watch out for shards. Magnets can explode upon violent connection, ejecting shards into the air. Eye protection is mandatory.
Finger safety
Big blocks can break fingers in a fraction of a second. Never put your hand betwixt two attracting surfaces.
Dust is flammable
Combustion risk: Neodymium dust is highly flammable. Do not process magnets in home conditions as this may cause fire.
