Strengths and weaknesses of rare earth magnets.
Advantages
- They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
- They are extremely resistant to demagnetization induced by external disturbances,
- Thanks to the metallic finish, the surface of nickel, gold, or silver-plated gives an elegant appearance,
- Magnets are characterized by very high magnetic induction on the outer side,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures reaching 230°C and above...
- In view of the ability of precise shaping and adaptation to individualized requirements, magnetic components can be created in a wide range of shapes and sizes, which expands the range of possible applications,
- Versatile presence in advanced technology sectors – they find application in hard drives, brushless drives, advanced medical instruments, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in small systems
Cons
- At strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- 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 secure oxidation and corrosion.
- We recommend cover - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex forms.
- Health risk resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the context of child safety. It is also worth noting that tiny parts of these products are able to complicate diagnosis medical when they are in the body.
- Due to expensive raw materials, their price is higher than average,
Holding force characteristics
Maximum holding power of the magnet – what affects it?
- using a sheet made of mild steel, serving as a magnetic yoke
- with a cross-section no less than 10 mm
- with an polished touching surface
- without the slightest air gap between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at room temperature
Impact of factors on magnetic holding capacity in practice
- Gap (betwixt the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
- Angle of force application – highest force is reached only during pulling at a 90° angle. The shear force of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick steel causes magnetic saturation, causing part of the power to be escaped to the other side.
- Plate material – mild steel attracts best. Higher carbon content reduce magnetic permeability and lifting capacity.
- Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Thermal environment – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Safety rules for work with NdFeB magnets
Caution required
Exercise caution. Neodymium magnets act from a long distance and snap with huge force, often faster than you can move away.
Crushing risk
Protect your hands. Two large magnets will join immediately with a force of massive weight, destroying anything in their path. Exercise extreme caution!
Data carriers
Do not bring magnets near a wallet, laptop, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.
Permanent damage
Monitor thermal conditions. Exposing the magnet to high heat will destroy its properties and pulling force.
Choking Hazard
Neodymium magnets are not suitable for play. Eating several magnets can lead to them pinching intestinal walls, which constitutes a direct threat to life and necessitates urgent medical intervention.
Mechanical processing
Drilling and cutting of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Magnetic interference
Be aware: neodymium magnets generate a field that disrupts precision electronics. Keep a safe distance from your phone, tablet, and navigation systems.
Sensitization to coating
Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation appears, immediately stop handling magnets and use protective gear.
Implant safety
People with a ICD should maintain an safe separation from magnets. The magnetism can disrupt the functioning of the implant.
Protective goggles
Watch out for shards. Magnets can explode upon uncontrolled impact, launching shards into the air. We recommend safety glasses.
