Advantages and disadvantages of rare earth magnets.
Benefits
- Their strength remains stable, and after around ten years it decreases only by ~1% (according to research),
- Neodymium magnets are characterized by extremely resistant to loss of magnetic properties caused by magnetic disturbances,
- In other words, due to the aesthetic surface of gold, the element looks attractive,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of detailed shaping and modifying to concrete applications,
- Significant place in advanced technology sectors – they are utilized in hard drives, brushless drives, medical equipment, also complex engineering applications.
- 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 secures the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Limited possibility of making threads in the magnet and complicated forms - recommended is cover - magnet mounting.
- Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that small elements of these devices are able to complicate diagnosis medical in case of swallowing.
- Due to neodymium price, their price is relatively high,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what affects it?
- on a plate made of mild steel, perfectly concentrating the magnetic field
- whose transverse dimension is min. 10 mm
- with an ideally smooth touching surface
- with total lack of distance (without impurities)
- during pulling in a direction vertical to the plane
- at room temperature
Determinants of practical lifting force of a magnet
- Gap (between the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to paint, corrosion or dirt).
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Plate thickness – insufficiently thick steel does not close the flux, causing part of the power to be wasted into the air.
- Material composition – not every steel reacts the same. Alloy additives weaken the attraction effect.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves field saturation. Rough surfaces weaken the grip.
- Temperature influence – high temperature weakens magnetic field. Too high temperature can permanently damage the magnet.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
Precautions when working with neodymium magnets
Combustion hazard
Fire hazard: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.
Phone sensors
Be aware: rare earth magnets produce a field that interferes with precision electronics. Keep a safe distance from your phone, device, and GPS.
Medical interference
Life threat: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Do not give to children
Product intended for adults. Small elements pose a choking risk, causing serious injuries. Keep away from children and animals.
Thermal limits
Standard neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. Damage is permanent.
Physical harm
Pinching hazard: The attraction force is so great that it can result in hematomas, crushing, and broken bones. Use thick gloves.
Safe distance
Very strong magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.
Allergic reactions
Nickel alert: The nickel-copper-nickel coating contains nickel. If redness happens, cease handling magnets and wear gloves.
Conscious usage
Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Eye protection
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
