Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- They do not lose magnetism, even during around ten years – the reduction in power is only ~1% (based on measurements),
- They retain their magnetic properties even under external field action,
- A magnet with a metallic silver surface has better aesthetics,
- Magnets exhibit huge magnetic induction on the working surface,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Possibility of exact shaping and optimizing to defined applications,
- Versatile presence in high-tech industry – they find application in hard drives, electromotive mechanisms, medical equipment, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in miniature devices
Limitations
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in realizing threads and complicated shapes in magnets, we recommend using cover - magnetic mount.
- Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- Due to neodymium price, their price exceeds standard values,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what affects it?
- using a plate made of mild steel, serving as a circuit closing element
- with a cross-section of at least 10 mm
- with an polished contact surface
- with total lack of distance (no impurities)
- during detachment in a direction perpendicular to the plane
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Chemical composition of the base – mild steel attracts best. Higher carbon content decrease magnetic properties and lifting capacity.
- Surface finish – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a minimal clearance between the magnet and the plate lowers the holding force.
Warnings
Danger to the youngest
Product intended for adults. Small elements can be swallowed, causing severe trauma. Keep out of reach of children and animals.
Operating temperature
Keep cool. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).
Cards and drives
Very strong magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.
Allergic reactions
Some people suffer from a contact allergy to nickel, which is the common plating for NdFeB magnets. Prolonged contact can result in a rash. It is best to wear protective gloves.
Machining danger
Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Magnet fragility
Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Wear goggles.
Handling guide
Use magnets with awareness. Their powerful strength can surprise even experienced users. Plan your moves and respect their power.
Serious injuries
Large magnets can break fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.
Threat to navigation
Remember: neodymium magnets produce a field that disrupts sensitive sensors. Maintain a safe distance from your phone, device, and GPS.
Health Danger
Life threat: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
