Strengths and weaknesses of Nd2Fe14B magnets.
Benefits
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (according to literature),
- Neodymium magnets are characterized by remarkably resistant to magnetic field loss caused by external interference,
- In other words, due to the reflective surface of gold, the element becomes visually attractive,
- The surface of neodymium magnets generates a unique magnetic field – this is one of their assets,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- In view of the potential of flexible shaping and adaptation to individualized solutions, neodymium magnets can be created in a variety of shapes and sizes, which expands the range of possible applications,
- Wide application in advanced technology sectors – they serve a role in magnetic memories, electric drive systems, precision medical tools, also technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Cons
- At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We recommend a housing - magnetic holder, due to difficulties in producing threads inside the magnet and complicated forms.
- Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these magnets can be problematic in diagnostics medical when they are in the body.
- With mass production the cost of neodymium magnets can be a barrier,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what it depends on?
- using a base made of low-carbon steel, functioning as a circuit closing element
- whose thickness is min. 10 mm
- characterized by even structure
- without the slightest clearance between the magnet and steel
- under perpendicular application of breakaway force (90-degree angle)
- in stable room temperature
Key elements affecting lifting force
- Air gap (between the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Direction of force – highest force is obtained only during perpendicular pulling. The force required to slide of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Steel grade – the best choice is high-permeability steel. Stainless steels may attract less.
- Surface finish – ideal contact is possible only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet’s surface and the plate lowers the holding force.
Safe handling of NdFeB magnets
Medical interference
Individuals with a heart stimulator must maintain an large gap from magnets. The magnetism can disrupt the functioning of the implant.
Bone fractures
Mind your fingers. Two powerful magnets will snap together instantly with a force of massive weight, crushing anything in their path. Be careful!
Dust is flammable
Dust produced during machining of magnets is flammable. Do not drill into magnets unless you are an expert.
Heat warning
Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Choking Hazard
Only for adults. Tiny parts pose a choking risk, leading to severe trauma. Store away from children and animals.
Allergy Warning
Studies show that nickel (standard magnet coating) is a common allergen. For allergy sufferers, avoid touching magnets with bare hands and select coated magnets.
Handling guide
Exercise caution. Rare earth magnets act from a distance and connect with massive power, often faster than you can move away.
Safe distance
Powerful magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.
Impact on smartphones
Remember: neodymium magnets produce a field that interferes with sensitive sensors. Keep a safe distance from your phone, tablet, and navigation systems.
Shattering risk
Beware of splinters. Magnets can fracture upon violent connection, launching sharp fragments into the air. Wear goggles.
