Pros and cons of Nd2Fe14B magnets.
Pros
- They do not lose power, even after approximately ten years – the reduction in power is only ~1% (theoretically),
- They retain their magnetic properties even under close interference source,
- In other words, due to the shiny surface of gold, the element gains a professional look,
- The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
- 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...
- Thanks to freedom in shaping and the capacity to modify to unusual requirements,
- Fundamental importance in future technologies – they are utilized in data components, drive modules, advanced medical instruments, as well as complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of producing nuts in the magnet and complex forms - recommended is a housing - magnet mounting.
- Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these devices can complicate diagnosis medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is economically unviable,
Lifting parameters
Maximum lifting force for a neodymium magnet – what it depends on?
- on a block made of mild steel, perfectly concentrating the magnetic flux
- possessing a thickness of minimum 10 mm to ensure full flux closure
- characterized by smoothness
- with zero gap (no impurities)
- under perpendicular force direction (90-degree angle)
- at room temperature
Impact of factors on magnetic holding capacity in practice
- Distance – the presence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Plate material – mild steel gives the best results. Higher carbon content reduce magnetic properties and holding force.
- Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Temperature influence – high temperature reduces magnetic field. Too high temperature can permanently damage the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under shearing force the holding force is lower. Additionally, even a slight gap between the magnet and the plate reduces the load capacity.
Warnings
Do not underestimate power
Exercise caution. Neodymium magnets act from a long distance and connect with massive power, often quicker than you can react.
Magnets are brittle
NdFeB magnets are ceramic materials, meaning they are very brittle. Clashing of two magnets leads to them cracking into shards.
Hand protection
Watch your fingers. Two large magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Be careful!
Heat warning
Control the heat. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and pulling force.
Fire risk
Fire warning: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.
This is not a toy
Neodymium magnets are not suitable for play. Accidental ingestion of several magnets may result in them pinching intestinal walls, which poses a direct threat to life and requires urgent medical intervention.
Danger to pacemakers
Life threat: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
GPS Danger
An intense magnetic field disrupts the operation of magnetometers in smartphones and GPS navigation. Do not bring magnets near a smartphone to prevent breaking the sensors.
Keep away from computers
Intense magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Sensitization to coating
Medical facts indicate that nickel (the usual finish) is a common allergen. If your skin reacts to metals, refrain from direct skin contact and opt for encased magnets.
