Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- They do not lose power, even after around 10 years – the decrease in strength is only ~1% (theoretically),
- Neodymium magnets are distinguished by extremely resistant to magnetic field loss caused by magnetic disturbances,
- A magnet with a metallic nickel surface is more attractive,
- Magnetic induction on the working layer of the magnet is maximum,
- 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...
- Thanks to modularity in constructing and the capacity to modify to client solutions,
- Significant place in advanced technology sectors – they find application in data components, electric drive systems, medical devices, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in miniature devices
Weaknesses
- At very strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's 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.
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Limited ability of creating threads in the magnet and complex shapes - recommended is cover - magnet mounting.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these devices can complicate diagnosis medical when they are in the body.
- With large orders the cost of neodymium magnets is a challenge,
Holding force characteristics
Highest magnetic holding force – what it depends on?
- on a plate made of structural steel, perfectly concentrating the magnetic field
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with an ground touching surface
- without the slightest insulating layer between the magnet and steel
- during pulling in a direction perpendicular to the plane
- at room temperature
Determinants of practical lifting force of a magnet
- Clearance – the presence of foreign body (rust, dirt, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Chemical composition of the base – mild steel attracts best. Alloy steels decrease magnetic permeability and lifting capacity.
- Surface structure – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Safety rules for work with neodymium magnets
Electronic hazard
Intense magnetic fields can erase data on credit cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Metal Allergy
Certain individuals experience a sensitization to nickel, which is the standard coating for neodymium magnets. Extended handling may cause skin redness. We recommend wear protective gloves.
Mechanical processing
Dust produced during machining of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Finger safety
Danger of trauma: The pulling power is so immense that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Life threat
For implant holders: Strong magnetic fields affect medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.
GPS and phone interference
Remember: neodymium magnets generate a field that confuses sensitive sensors. Maintain a safe distance from your mobile, device, and GPS.
Maximum temperature
Monitor thermal conditions. Exposing the magnet to high heat will ruin its properties and strength.
Shattering risk
Watch out for shards. Magnets can fracture upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Powerful field
Handle with care. Neodymium magnets attract from a distance and connect with massive power, often faster than you can move away.
Do not give to children
Absolutely keep magnets away from children. Ingestion danger is high, and the effects of magnets connecting inside the body are fatal.
