Pros and cons of Nd2Fe14B magnets.
Benefits
- They do not lose magnetism, even during nearly 10 years – the reduction in power is only ~1% (theoretically),
- Magnets perfectly resist against demagnetization caused by foreign field sources,
- By applying a smooth layer of silver, the element has an elegant look,
- Magnets are distinguished by extremely high magnetic induction on the active area,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of precise shaping and modifying to individual requirements,
- Universal use in electronics industry – they are utilized in mass storage devices, brushless drives, medical devices, as well as modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- We recommend casing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex forms.
- Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. Furthermore, small components of these devices are able to be problematic in diagnostics medical in case of swallowing.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- using a plate made of low-carbon steel, acting as a ideal flux conductor
- whose thickness equals approx. 10 mm
- with an ground touching surface
- without any clearance between the magnet and steel
- under perpendicular application of breakaway force (90-degree angle)
- in temp. approx. 20°C
Practical lifting capacity: influencing factors
- Air gap (between the magnet and the metal), since even a tiny 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 dirt).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Plate material – mild steel attracts best. Alloy admixtures reduce magnetic permeability and lifting capacity.
- Plate texture – ground elements guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
- Thermal environment – heating the magnet results in weakening of force. Check the thermal limit for a given model.
Lifting capacity testing was conducted 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’s surface and the plate decreases the load capacity.
Safety rules for work with neodymium magnets
Keep away from children
These products are not toys. Swallowing several magnets can lead to them attracting across intestines, which poses a severe health hazard and necessitates immediate surgery.
Keep away from computers
Do not bring magnets close to a purse, laptop, or TV. The magnetic field can destroy these devices and erase data from cards.
Flammability
Combustion risk: Neodymium dust is explosive. Do not process magnets in home conditions as this may cause fire.
Finger safety
Big blocks can break fingers in a fraction of a second. Under no circumstances place your hand between two attracting surfaces.
Eye protection
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching shards into the air. We recommend safety glasses.
Do not underestimate power
Be careful. Rare earth magnets act from a long distance and connect with massive power, often quicker than you can react.
Heat warning
Standard neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. This process is irreversible.
Life threat
Individuals with a pacemaker must maintain an large gap from magnets. The magnetic field can stop the functioning of the life-saving device.
Compass and GPS
GPS units and smartphones are highly sensitive to magnetic fields. Direct contact with a strong magnet can permanently damage the internal compass in your phone.
Sensitization to coating
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, cease handling magnets and wear gloves.
