Strengths and weaknesses of Nd2Fe14B magnets.
Benefits
- They do not lose strength, even after approximately ten years – the decrease in lifting capacity is only ~1% (according to tests),
- They are resistant to demagnetization induced by external magnetic fields,
- The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to look better,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of detailed modeling and optimizing to individual needs,
- Key role in innovative solutions – they are utilized in data components, electric drive systems, advanced medical instruments, also technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic holder, due to difficulties in creating threads inside the magnet and complicated forms.
- Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Furthermore, small elements of these products can be problematic in diagnostics medical in case of swallowing.
- Due to expensive raw materials, their price exceeds standard values,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- with the contact of a sheet made of special test steel, guaranteeing maximum field concentration
- with a thickness of at least 10 mm
- with an ground touching surface
- without any insulating layer between the magnet and steel
- during pulling in a direction perpendicular to the plane
- at standard ambient temperature
Determinants of practical lifting force of a magnet
- Distance (between the magnet and the plate), because even a tiny clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to paint, rust or debris).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Steel type – mild steel attracts best. Alloy admixtures decrease magnetic permeability and holding force.
- Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, in contrast under parallel forces the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet and the plate reduces the load capacity.
H&S for magnets
Magnets are brittle
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets leads to them shattering into small pieces.
Powerful field
Exercise caution. Neodymium magnets act from a long distance and snap with massive power, often faster than you can react.
Heat warning
Standard neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
Crushing force
Protect your hands. Two powerful magnets will snap together immediately with a force of massive weight, destroying everything in their path. Exercise extreme caution!
Threat to navigation
Remember: neodymium magnets generate a field that interferes with sensitive sensors. Keep a separation from your mobile, device, and navigation systems.
Cards and drives
Very strong magnetic fields can destroy records on payment cards, hard drives, and storage devices. Maintain a gap of min. 10 cm.
This is not a toy
Product intended for adults. Tiny parts pose a choking risk, causing serious injuries. Keep away from kids and pets.
Dust is flammable
Dust created during machining of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Nickel allergy
Studies show that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, refrain from touching magnets with bare hands and select encased magnets.
Implant safety
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
