Advantages as well as disadvantages of neodymium magnets.
Strengths
- They have stable power, and over around 10 years their performance decreases symbolically – ~1% (in testing),
- They do not lose their magnetic properties even under strong external field,
- In other words, due to the smooth finish of silver, the element gains visual value,
- Neodymium magnets generate maximum magnetic induction on a contact point, which increases force concentration,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to freedom in shaping and the capacity to modify to complex applications,
- Fundamental importance in future technologies – they are utilized in hard drives, electromotive mechanisms, medical devices, also complex engineering applications.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Weaknesses
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing 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 lose their strength at high temperatures. To prevent this, we advise 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 immune to moisture, in case of application outdoors
- We suggest casing - magnetic holder, due to difficulties in creating threads inside the magnet and complicated shapes.
- Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, small components of these products can disrupt the diagnostic process medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is economically unviable,
Pull force analysis
Maximum holding power of the magnet – what it depends on?
- with the contact of a sheet made of low-carbon steel, ensuring full magnetic saturation
- whose transverse dimension reaches at least 10 mm
- with an polished contact surface
- under conditions of ideal adhesion (surface-to-surface)
- for force applied at a right angle (pull-off, not shear)
- in neutral thermal conditions
Magnet lifting force in use – key factors
- Air gap (betwixt the magnet and the metal), because even a very small clearance (e.g. 0.5 mm) results in a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Steel grade – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
- Surface finish – ideal contact is possible only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Crushing risk
Watch your fingers. Two powerful magnets will join instantly with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
Warning for heart patients
Life threat: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Magnets are brittle
Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Do not give to children
These products are not intended for children. Accidental ingestion of multiple magnets can lead to them pinching intestinal walls, which constitutes a direct threat to life and requires urgent medical intervention.
Phone sensors
Navigation devices and mobile phones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Mechanical processing
Dust created during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Powerful field
Handle magnets with awareness. Their immense force can surprise even experienced users. Stay alert and respect their force.
Electronic hazard
Powerful magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
Heat sensitivity
Standard neodymium magnets (grade N) lose power when the temperature exceeds 80°C. This process is irreversible.
Skin irritation risks
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, cease handling magnets and wear gloves.
