Pros and cons of Nd2Fe14B magnets.
Pros
- They retain full power for around ten years – the drop is just ~1% (according to analyses),
- They maintain their magnetic properties even under strong external field,
- Thanks to the shiny finish, the layer of nickel, gold, or silver gives an visually attractive appearance,
- The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures reaching 230°C and above...
- Thanks to flexibility in designing and the capacity to modify to specific needs,
- Huge importance in modern technologies – they are used in data components, electromotive mechanisms, advanced medical instruments, also other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Disadvantages
- Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only protects them against impacts but also raises their durability
- NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- 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, when using outdoors
- We suggest a housing - magnetic holder, due to difficulties in producing threads inside the magnet and complex shapes.
- Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that tiny parts of these magnets are able to disrupt the diagnostic process medical after entering the body.
- Due to expensive raw materials, their price is higher than average,
Lifting parameters
Maximum lifting force for a neodymium magnet – what affects it?
- on a block made of structural steel, perfectly concentrating the magnetic flux
- whose transverse dimension equals approx. 10 mm
- characterized by smoothness
- under conditions of gap-free contact (metal-to-metal)
- for force applied at a right angle (in the magnet axis)
- at temperature room level
Magnet lifting force in use – key factors
- Distance (between the magnet and the metal), because even a microscopic clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
- Load vector – highest force is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Stainless steels may have worse magnetic properties.
- Plate texture – ground elements guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, 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 lowers the holding force.
Safety rules for work with NdFeB magnets
Impact on smartphones
Note: rare earth magnets generate a field that interferes with sensitive sensors. Keep a safe distance from your phone, device, and navigation systems.
Shattering risk
Beware of splinters. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Wear goggles.
Physical harm
Risk of injury: The pulling power is so great that it can result in hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Heat warning
Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. Damage is permanent.
This is not a toy
Neodymium magnets are not toys. Accidental ingestion of a few magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and requires urgent medical intervention.
Avoid contact if allergic
It is widely known that the nickel plating (standard magnet coating) is a potent allergen. If your skin reacts to metals, prevent touching magnets with bare hands and opt for encased magnets.
Conscious usage
Use magnets consciously. Their powerful strength can surprise even experienced users. Be vigilant and respect their power.
Mechanical processing
Fire warning: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Electronic hazard
Powerful magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.
Medical implants
People with a heart stimulator have to maintain an absolute distance from magnets. The magnetism can disrupt the functioning of the life-saving device.
