Strengths and weaknesses of Nd2Fe14B magnets.
Strengths
- They retain attractive force for almost ten years – the drop is just ~1% (according to analyses),
- They have excellent resistance to magnetic field loss as a result of external fields,
- In other words, due to the shiny surface of gold, the element is aesthetically pleasing,
- Neodymium magnets achieve maximum magnetic induction on a small surface, which ensures high operational effectiveness,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of exact shaping and modifying to precise conditions,
- Significant place in high-tech industry – they find application in hard drives, motor assemblies, medical equipment, and modern systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Limitations
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend casing - magnetic mount, due to difficulties in creating threads inside the magnet and complicated shapes.
- Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- Due to neodymium price, their price exceeds standard values,
Pull force analysis
Maximum magnetic pulling force – what affects it?
- using a sheet made of mild steel, serving as a circuit closing element
- whose transverse dimension equals approx. 10 mm
- characterized by lack of roughness
- with direct contact (no paint)
- during detachment in a direction perpendicular to the plane
- in temp. approx. 20°C
Practical aspects of lifting capacity – factors
- Distance – the presence of any layer (paint, dirt, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Plate material – mild steel gives the best results. Alloy steels lower magnetic permeability and holding force.
- Surface finish – full contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Temperature – heating the magnet results in weakening of induction. Check the thermal limit 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 attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet and the plate decreases the lifting capacity.
Safe handling of NdFeB magnets
GPS Danger
An intense magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Keep magnets near a smartphone to prevent damaging the sensors.
Combustion hazard
Combustion risk: Neodymium dust is highly flammable. Do not process magnets without safety gear as this may cause fire.
Thermal limits
Regular neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.
Bone fractures
Mind your fingers. Two large magnets will join immediately with a force of massive weight, crushing everything in their path. Be careful!
Implant safety
For implant holders: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.
Keep away from children
Product intended for adults. Small elements pose a choking risk, causing serious injuries. Store out of reach of children and animals.
Nickel coating and allergies
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness occurs, cease working with magnets and wear gloves.
Handling rules
Use magnets with awareness. Their huge power can shock even experienced users. Plan your moves and do not underestimate their force.
Threat to electronics
Do not bring magnets near a wallet, computer, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.
Risk of cracking
Beware of splinters. Magnets can fracture upon violent connection, ejecting shards into the air. Eye protection is mandatory.
