Advantages and disadvantages of Nd2Fe14B magnets.
Pros
- They retain full power for almost ten years – the loss is just ~1% (based on simulations),
- They possess excellent resistance to weakening of magnetic properties as a result of opposing magnetic fields,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures reaching 230°C and above...
- Possibility of accurate shaping and modifying to defined conditions,
- Fundamental importance in high-tech industry – they find application in data components, drive modules, advanced medical instruments, and other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Cons
- At very strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- Due to limitations in producing threads and complicated forms in magnets, we propose using cover - magnetic holder.
- Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. Additionally, tiny parts of these products are able to be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Maximum holding power of the magnet – what affects it?
- on a block made of mild steel, effectively closing the magnetic flux
- whose thickness reaches at least 10 mm
- characterized by lack of roughness
- under conditions of no distance (surface-to-surface)
- for force applied at a right angle (pull-off, not shear)
- at temperature room level
Lifting capacity in real conditions – factors
- Distance (between the magnet and the metal), because even a very small distance (e.g. 0.5 mm) can cause a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Material composition – not every steel attracts identically. High carbon content weaken the attraction effect.
- Smoothness – ideal contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Temperature – temperature increase results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate reduces the holding force.
Safety rules for work with NdFeB magnets
Heat sensitivity
Regular neodymium magnets (N-type) lose power when the temperature exceeds 80°C. The loss of strength is permanent.
Fire warning
Fire hazard: Neodymium dust is highly flammable. Do not process magnets in home conditions as this may cause fire.
Implant safety
Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Crushing risk
Large magnets can break fingers in a fraction of a second. Do not place your hand betwixt two strong magnets.
Caution required
Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Warning for allergy sufferers
Nickel alert: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, cease working with magnets and use protective gear.
Data carriers
Avoid bringing magnets close to a wallet, computer, or TV. The magnetism can destroy these devices and wipe information from cards.
Choking Hazard
Only for adults. Tiny parts can be swallowed, causing severe trauma. Store out of reach of kids and pets.
GPS Danger
Remember: neodymium magnets produce a field that interferes with precision electronics. Keep a safe distance from your mobile, device, and navigation systems.
Shattering risk
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets leads to them shattering into small pieces.
