Advantages as well as disadvantages of Nd2Fe14B magnets.
Advantages
- They have unchanged lifting capacity, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
- They have excellent resistance to magnetic field loss due to external magnetic sources,
- Thanks to the shimmering finish, the surface of nickel, gold-plated, or silver-plated gives an elegant appearance,
- Magnets possess very high magnetic induction on the outer layer,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Thanks to versatility in constructing and the capacity to customize to client solutions,
- Versatile presence in modern industrial fields – they are used in hard drives, brushless drives, medical devices, and complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- Neodymium magnets demagnetize 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 very resistant to heat
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Limited ability of making nuts in the magnet and complicated forms - preferred is cover - mounting mechanism.
- Health risk related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the context of child safety. Furthermore, small components of these devices can be problematic in diagnostics medical in case of swallowing.
- With mass production the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum holding power of the magnet – what it depends on?
- with the application of a yoke made of low-carbon steel, ensuring maximum field concentration
- with a thickness no less than 10 mm
- with a plane cleaned and smooth
- under conditions of no distance (metal-to-metal)
- during detachment in a direction vertical to the plane
- at ambient temperature room level
Practical lifting capacity: influencing factors
- Distance – the presence of any layer (rust, tape, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Steel grade – ideal substrate is pure iron steel. Stainless steels may generate lower lifting capacity.
- Smoothness – ideal contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet and the plate decreases the holding force.
Warnings
Crushing force
Risk of injury: The pulling power is so immense that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.
Adults only
Adult use only. Tiny parts can be swallowed, leading to intestinal necrosis. Keep away from kids and pets.
Fire risk
Mechanical processing of neodymium magnets poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
GPS Danger
GPS units and smartphones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.
Conscious usage
Handle magnets with awareness. Their immense force can surprise even experienced users. Be vigilant and do not underestimate their power.
Keep away from computers
Intense magnetic fields can erase data on payment cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
Pacemakers
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Fragile material
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.
Skin irritation risks
It is widely known that nickel (the usual finish) is a potent allergen. If you have an allergy, avoid touching magnets with bare hands or opt for encased magnets.
Operating temperature
Monitor thermal conditions. Exposing the magnet to high heat will destroy its properties and pulling force.
