Strengths as well as weaknesses of Nd2Fe14B magnets.
Benefits
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (based on calculations),
- Neodymium magnets are characterized by exceptionally resistant to magnetic field loss caused by external interference,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnets possess impressive magnetic induction on the surface,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to flexibility in constructing and the capacity to customize to client solutions,
- Fundamental importance in modern technologies – they are used in HDD drives, electric motors, advanced medical instruments, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in compact constructions
Limitations
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating threads and complex forms in magnets, we propose using cover - magnetic mechanism.
- Health risk resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these devices can be problematic in diagnostics medical after entering the body.
- Due to expensive raw materials, their price is relatively high,
Pull force analysis
Detachment force of the magnet in optimal conditions – what contributes to it?
- with the use of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- possessing a massiveness of at least 10 mm to avoid saturation
- with a plane free of scratches
- with zero gap (without coatings)
- during pulling in a direction vertical to the plane
- at temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Direction of force – maximum parameter is reached only during pulling at a 90° angle. The shear force of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Steel type – mild steel attracts best. Alloy admixtures lower magnetic permeability and holding force.
- Surface condition – smooth surfaces ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
- Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was determined with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under attempts to slide the magnet the load capacity is reduced by as much as 5 times. Moreover, even a small distance between the magnet’s surface and the plate lowers the load capacity.
Precision electronics
Navigation devices and mobile phones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.
Health Danger
Warning for patients: Strong magnetic fields disrupt medical devices. Keep minimum 30 cm distance or request help to handle the magnets.
Operating temperature
Monitor thermal conditions. Heating the magnet to high heat will ruin its properties and pulling force.
Mechanical processing
Machining of neodymium magnets carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Safe operation
Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Sensitization to coating
Certain individuals suffer from a contact allergy to Ni, which is the standard coating for neodymium magnets. Frequent touching may cause a rash. We recommend use safety gloves.
Beware of splinters
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
This is not a toy
These products are not suitable for play. Swallowing multiple magnets can lead to them attracting across intestines, which poses a critical condition and requires urgent medical intervention.
Magnetic media
Very strong magnetic fields can erase data on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Bone fractures
Danger of trauma: The pulling power is so great that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.
