Pros as well as cons of neodymium magnets.
Pros
- They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (based on calculations),
- They retain their magnetic properties even under strong external field,
- By applying a smooth layer of silver, the element gains an elegant look,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- In view of the ability of free forming and adaptation to custom requirements, neodymium magnets can be created in a broad palette of geometric configurations, which amplifies use scope,
- Key role in future technologies – they are commonly used in magnetic memories, electric drive systems, advanced medical instruments, and modern systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Disadvantages
- To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend a housing - magnetic holder, due to difficulties in realizing nuts inside the magnet and complex shapes.
- Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Additionally, small elements of these products can be problematic in diagnostics medical after entering the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Pull force analysis
Maximum lifting force for a neodymium magnet – what affects it?
- on a base made of structural steel, optimally conducting the magnetic field
- possessing a thickness of min. 10 mm to ensure full flux closure
- with an ideally smooth touching surface
- without the slightest air gap between the magnet and steel
- under perpendicular application of breakaway force (90-degree angle)
- at ambient temperature room level
Determinants of practical lifting force of a magnet
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Material type – the best choice is pure iron steel. Hardened steels may have worse magnetic properties.
- Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, however under shearing force the holding force is lower. Moreover, even a slight gap between the magnet and the plate lowers the holding force.
H&S for magnets
Safe distance
Do not bring magnets close to a wallet, computer, or screen. The magnetism can permanently damage these devices and erase data from cards.
Life threat
For implant holders: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
Compass and GPS
Navigation devices and mobile phones are highly susceptible to magnetism. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
Demagnetization risk
Do not overheat. NdFeB magnets are susceptible to heat. If you need operation above 80°C, look for HT versions (H, SH, UH).
Immense force
Handle magnets with awareness. Their huge power can shock even experienced users. Plan your moves and respect their power.
Fire warning
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Material brittleness
Watch out for shards. Magnets can explode upon violent connection, launching sharp fragments into the air. Wear goggles.
Skin irritation risks
It is widely known that the nickel plating (the usual finish) is a common allergen. For allergy sufferers, refrain from touching magnets with bare hands and select coated magnets.
Swallowing risk
Product intended for adults. Tiny parts can be swallowed, leading to severe trauma. Store out of reach of kids and pets.
Physical harm
Pinching hazard: The attraction force is so immense that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
