Pros and cons of Nd2Fe14B magnets.
Strengths
- They do not lose strength, even over nearly ten years – the decrease in power is only ~1% (theoretically),
- They feature excellent resistance to magnetic field loss when exposed to external magnetic sources,
- A magnet with a smooth nickel surface is more attractive,
- Magnets are characterized by exceptionally strong magnetic induction on the surface,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Due to the potential of flexible shaping and customization to unique projects, neodymium magnets can be produced in a variety of forms and dimensions, which makes them more universal,
- Fundamental importance in advanced technology sectors – they find application in hard drives, electromotive mechanisms, precision medical tools, also industrial machines.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Cons
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- We warn that neodymium magnets can reduce their strength 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
- Due to limitations in producing nuts and complex forms in magnets, we propose using casing - magnetic holder.
- Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these devices are able to disrupt the diagnostic process medical when they are in the body.
- With large orders the cost of neodymium magnets is a challenge,
Holding force characteristics
Maximum holding power of the magnet – what contributes to it?
- using a plate made of high-permeability steel, acting as a magnetic yoke
- possessing a massiveness of at least 10 mm to avoid saturation
- characterized by lack of roughness
- with total lack of distance (no paint)
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature room level
Practical lifting capacity: influencing factors
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Plate material – low-carbon steel attracts best. Higher carbon content lower magnetic permeability and lifting capacity.
- Surface structure – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet and the plate decreases the lifting capacity.
Safe handling of neodymium magnets
Bone fractures
Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!
Threat to navigation
Remember: neodymium magnets generate a field that disrupts sensitive sensors. Maintain a safe distance from your mobile, tablet, and GPS.
Magnet fragility
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
Do not underestimate power
Handle with care. Neodymium magnets attract from a distance and snap with huge force, often faster than you can react.
Adults only
Absolutely store magnets out of reach of children. Choking hazard is high, and the effects of magnets clamping inside the body are very dangerous.
Danger to pacemakers
Warning for patients: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or request help to work with the magnets.
Flammability
Mechanical processing of neodymium magnets carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Protect data
Powerful magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
Operating temperature
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
Nickel coating and allergies
Nickel alert: The nickel-copper-nickel coating contains nickel. If skin irritation occurs, immediately stop handling magnets and wear gloves.
