Advantages as well as disadvantages of Nd2Fe14B magnets.
Benefits
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
- Neodymium magnets are characterized by remarkably resistant to demagnetization caused by external field sources,
- A magnet with a metallic nickel surface is more attractive,
- Magnets are distinguished by extremely high magnetic induction on the active area,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of precise forming and modifying to concrete requirements,
- Versatile presence in advanced technology sectors – they find application in HDD drives, electric drive systems, medical devices, as well as multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Cons
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- 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 start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in producing threads and complicated forms in magnets, we recommend using cover - magnetic mechanism.
- Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child safety. Additionally, tiny parts of these magnets can disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Maximum lifting capacity of the magnet – what contributes to it?
- using a sheet made of high-permeability steel, acting as a circuit closing element
- with a cross-section of at least 10 mm
- characterized by lack of roughness
- without any clearance between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at room temperature
Key elements affecting lifting force
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Load vector – maximum parameter is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Material composition – not every steel attracts identically. High carbon content weaken the attraction effect.
- Surface finish – full contact is possible only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Thermal environment – temperature increase results in weakening of induction. Check the thermal limit for a given model.
Lifting capacity was measured using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet and the plate lowers the load capacity.
Safety rules for work with neodymium magnets
Do not underestimate power
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.
Swallowing risk
Adult use only. Tiny parts pose a choking risk, causing severe trauma. Store out of reach of kids and pets.
Mechanical processing
Powder generated during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Safe distance
Data protection: Strong magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, timepieces).
Magnet fragility
Despite metallic appearance, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Crushing force
Pinching hazard: The attraction force is so immense that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
GPS Danger
Navigation devices and mobile phones are extremely susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Skin irritation risks
A percentage of the population experience a hypersensitivity to nickel, which is the common plating for neodymium magnets. Extended handling may cause skin redness. It is best to use protective gloves.
Danger to pacemakers
For implant holders: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.
Do not overheat magnets
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
