Advantages and disadvantages of rare earth magnets.
Advantages
- They do not lose strength, even over approximately 10 years – the reduction in strength is only ~1% (based on measurements),
- Neodymium magnets remain highly resistant to magnetic field loss caused by magnetic disturbances,
- By using a reflective coating of gold, the element gains an nice look,
- They are known for high magnetic induction at the operating surface, which affects their effectiveness,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures approaching 230°C and above...
- Possibility of detailed modeling and modifying to specific needs,
- Fundamental importance in modern technologies – they are commonly used in hard drives, electric motors, precision medical tools, also multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Cons
- To avoid cracks under impact, 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 weakening 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 when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited possibility of making threads in the magnet and complex shapes - preferred is casing - magnet mounting.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which gains importance in the context of child safety. Furthermore, small components of these magnets are able to be problematic in diagnostics medical after entering the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Lifting parameters
Maximum lifting capacity of the magnet – what it depends on?
- with the contact of a sheet made of low-carbon steel, ensuring maximum field concentration
- possessing a massiveness of minimum 10 mm to avoid saturation
- with a surface free of scratches
- with total lack of distance (without impurities)
- for force acting at a right angle (pull-off, not shear)
- at room temperature
Magnet lifting force in use – key factors
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Material composition – not every steel reacts the same. High carbon content worsen the attraction effect.
- Base smoothness – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, however under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate decreases the holding force.
Precautions when working with NdFeB magnets
No play value
NdFeB magnets are not suitable for play. Swallowing multiple magnets can lead to them pinching intestinal walls, which poses a critical condition and necessitates urgent medical intervention.
Demagnetization risk
Keep cool. Neodymium magnets are susceptible to temperature. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Threat to navigation
Navigation devices and mobile phones are highly sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
Material brittleness
Beware of splinters. Magnets can explode upon violent connection, ejecting shards into the air. Wear goggles.
Dust is flammable
Fire warning: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.
Life threat
Life threat: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Conscious usage
Be careful. Rare earth magnets attract from a long distance and snap with huge force, often faster than you can move away.
Sensitization to coating
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, immediately stop handling magnets and wear gloves.
Magnetic media
Avoid bringing magnets near a purse, computer, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
Crushing risk
Watch your fingers. Two powerful magnets will join immediately with a force of massive weight, destroying anything in their path. Be careful!
