Advantages as well as disadvantages of Nd2Fe14B magnets.
Benefits
- They have constant strength, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
- Magnets perfectly resist against demagnetization caused by external fields,
- Thanks to the metallic finish, the layer of nickel, gold-plated, or silver-plated gives an aesthetic appearance,
- Magnets have very high magnetic induction on the working surface,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Due to the possibility of flexible shaping and adaptation to unique solutions, neodymium magnets can be created in a broad palette of geometric configurations, which makes them more universal,
- Versatile presence in advanced technology sectors – they find application in data components, motor assemblies, precision medical tools, also industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- At strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Limited possibility of creating threads in the magnet and complex forms - recommended is casing - magnetic holder.
- Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. Additionally, small elements of these products can disrupt the diagnostic process medical in case of swallowing.
- Due to expensive raw materials, their price exceeds standard values,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what affects it?
- with the use of a sheet made of special test steel, ensuring full magnetic saturation
- with a cross-section of at least 10 mm
- characterized by lack of roughness
- without any clearance between the magnet and steel
- during detachment in a direction perpendicular to the plane
- at ambient temperature approx. 20 degrees Celsius
Impact of factors on magnetic holding capacity in practice
- Distance (between the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to paint, rust or dirt).
- Load vector – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Material type – the best choice is high-permeability steel. Cast iron may have worse magnetic properties.
- Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
- Temperature influence – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity was measured using a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate decreases the lifting capacity.
H&S for magnets
Phone sensors
Be aware: rare earth magnets generate a field that confuses precision electronics. Keep a separation from your mobile, device, and navigation systems.
Risk of cracking
Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Impact of two magnets will cause them shattering into small pieces.
Heat sensitivity
Monitor thermal conditions. Exposing the magnet to high heat will ruin its magnetic structure and strength.
Immense force
Use magnets with awareness. Their powerful strength can surprise even professionals. Plan your moves and do not underestimate their force.
Serious injuries
Risk of injury: The pulling power is so great that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Life threat
People with a ICD must keep an large gap from magnets. The magnetism can stop the operation of the implant.
Fire risk
Drilling and cutting of neodymium magnets carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Sensitization to coating
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, immediately stop handling magnets and use protective gear.
Magnetic media
Data protection: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).
No play value
Product intended for adults. Small elements can be swallowed, leading to serious injuries. Keep out of reach of children and animals.
