Advantages as well as disadvantages of Nd2Fe14B magnets.
Advantages
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (according to literature),
- They show high resistance to demagnetization induced by presence of other magnetic fields,
- A magnet with a shiny gold surface has an effective appearance,
- The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to the possibility of accurate shaping and customization to specialized projects, neodymium magnets can be produced in a variety of shapes and sizes, which makes them more universal,
- Fundamental importance in innovative solutions – they are commonly used in computer drives, electric drive systems, diagnostic systems, and complex engineering applications.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Limited ability of creating nuts in the magnet and complex forms - preferred is cover - magnet mounting.
- Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child safety. Furthermore, small components of these magnets are able to disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Maximum lifting capacity of the magnet – what it depends on?
- on a base made of mild steel, optimally conducting the magnetic flux
- whose thickness is min. 10 mm
- with a surface cleaned and smooth
- without the slightest insulating layer between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at ambient temperature room level
Determinants of practical lifting force of a magnet
- Clearance – existence of foreign body (rust, dirt, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Steel type – mild steel gives the best results. Alloy admixtures lower magnetic properties and holding force.
- Surface condition – ground elements ensure maximum contact, which improves field saturation. Rough surfaces reduce efficiency.
- Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
Precautions when working with NdFeB magnets
Dust is flammable
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Danger to pacemakers
Individuals with a pacemaker must keep an absolute distance from magnets. The magnetism can stop the operation of the implant.
Finger safety
Danger of trauma: The pulling power is so immense that it can result in hematomas, pinching, and broken bones. Use thick gloves.
Thermal limits
Regular neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Beware of splinters
Protect your eyes. Magnets can explode upon violent connection, ejecting sharp fragments into the air. We recommend safety glasses.
Do not give to children
These products are not suitable for play. Eating several magnets may result in them attracting across intestines, which constitutes a severe health hazard and necessitates urgent medical intervention.
Nickel coating and allergies
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If redness appears, immediately stop handling magnets and wear gloves.
Conscious usage
Handle with care. Neodymium magnets attract from a long distance and connect with huge force, often faster than you can react.
Data carriers
Do not bring magnets close to a wallet, computer, or screen. The magnetism can permanently damage these devices and erase data from cards.
Compass and GPS
Be aware: neodymium magnets generate a field that confuses precision electronics. Keep a safe distance from your phone, device, and GPS.
