Strengths as well as weaknesses of rare earth magnets.
Benefits
- They have unchanged lifting capacity, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
- Neodymium magnets prove to be exceptionally resistant to demagnetization caused by external field sources,
- Thanks to the metallic finish, the coating of Ni-Cu-Ni, gold, or silver gives an visually attractive appearance,
- The surface of neodymium magnets generates a unique magnetic field – this is one of their assets,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to modularity in shaping and the ability to modify to unusual requirements,
- Universal use in electronics industry – they are utilized in hard drives, brushless drives, medical equipment, and modern systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
- We warn that neodymium magnets can lose 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 start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- We recommend casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Possible danger related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that small components of these products are able to be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what affects it?
- using a sheet made of high-permeability steel, serving as a ideal flux conductor
- whose transverse dimension equals approx. 10 mm
- with an ideally smooth contact surface
- with total lack of distance (no impurities)
- under axial application of breakaway force (90-degree angle)
- at conditions approx. 20°C
Practical aspects of lifting capacity – factors
- Distance (betwixt the magnet and the metal), because even a very small clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Steel type – mild steel gives the best results. Higher carbon content reduce magnetic properties and holding force.
- Base smoothness – the more even the plate, the larger the contact zone and higher the lifting capacity. Roughness acts like micro-gaps.
- Temperature influence – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the holding force is lower. Additionally, even a small distance between the magnet and the plate reduces the holding force.
Safety rules for work with NdFeB magnets
Permanent damage
Watch the temperature. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.
Impact on smartphones
Remember: neodymium magnets generate a field that disrupts sensitive sensors. Maintain a separation from your mobile, tablet, and navigation systems.
Protective goggles
Protect your eyes. Magnets can fracture upon violent connection, ejecting shards into the air. We recommend safety glasses.
Allergy Warning
Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, cease handling magnets and wear gloves.
Do not underestimate power
Before starting, check safety instructions. Sudden snapping can break the magnet or injure your hand. Be predictive.
Product not for children
Neodymium magnets are not toys. Eating a few magnets can lead to them connecting inside the digestive tract, which constitutes a critical condition and requires urgent medical intervention.
Pacemakers
Individuals with a ICD must keep an safe separation from magnets. The magnetism can disrupt the functioning of the life-saving device.
Combustion hazard
Fire warning: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.
Pinching danger
Watch your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Electronic hazard
Powerful magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Stay away of at least 10 cm.
