Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- They retain full power for around 10 years – the drop is just ~1% (based on simulations),
- They are noted for resistance to demagnetization induced by external disturbances,
- By using a decorative coating of gold, the element gains an aesthetic look,
- Neodymium magnets deliver maximum magnetic induction on a small surface, which increases force concentration,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of custom machining as well as adapting to precise conditions,
- Versatile presence in advanced technology sectors – they find application in computer drives, brushless drives, medical devices, also modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Disadvantages
- At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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 start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in producing nuts and complicated shapes in magnets, we propose using casing - magnetic holder.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child safety. It is also worth noting that small elements of these devices can complicate diagnosis medical when they are in the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what affects it?
- on a plate made of structural steel, optimally conducting the magnetic flux
- whose transverse dimension reaches at least 10 mm
- with an ground touching surface
- under conditions of no distance (metal-to-metal)
- under axial application of breakaway force (90-degree angle)
- in neutral thermal conditions
Key elements affecting lifting force
- Gap (between the magnet and the metal), as even a very small distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Angle of force application – highest force is available only during perpendicular pulling. The force required to slide of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Metal type – not every steel reacts the same. High carbon content worsen the attraction effect.
- Plate texture – ground elements ensure maximum contact, which increases force. Rough surfaces weaken the grip.
- Thermal environment – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
Warnings
Maximum temperature
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.
Skin irritation risks
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, cease handling magnets and wear gloves.
Finger safety
Large magnets can break fingers in a fraction of a second. Do not place your hand between two attracting surfaces.
Combustion hazard
Drilling and cutting of neodymium magnets poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Cards and drives
Powerful magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.
Keep away from electronics
GPS units and mobile phones are highly susceptible to magnetic fields. Direct contact with a strong magnet can ruin the sensors in your phone.
Medical implants
Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Choking Hazard
Only for adults. Tiny parts pose a choking risk, leading to intestinal necrosis. Store away from children and animals.
Eye protection
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Safe operation
Use magnets consciously. Their huge power can surprise even professionals. Plan your moves and respect their force.
