Advantages as well as disadvantages of Nd2Fe14B magnets.
Advantages
- They retain full power for around ten years – the drop is just ~1% (in theory),
- They have excellent resistance to magnetic field loss when exposed to external magnetic sources,
- A magnet with a metallic gold surface has better aesthetics,
- Magnetic induction on the working part of the magnet is extremely intense,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures reaching 230°C and above...
- Considering the option of free molding and customization to specialized projects, neodymium magnets can be created in a wide range of forms and dimensions, which makes them more universal,
- Key role in modern industrial fields – they are commonly used in hard drives, brushless drives, advanced medical instruments, as well as other advanced devices.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise 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 resistant to moisture, in case of application outdoors
- Limited ability of creating threads in the magnet and complicated forms - preferred is cover - magnet mounting.
- Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small components of these magnets are able to be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what affects it?
- with the use of a yoke made of special test steel, ensuring maximum field concentration
- whose transverse dimension is min. 10 mm
- characterized by lack of roughness
- without the slightest clearance between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at standard ambient temperature
Practical lifting capacity: influencing factors
- Distance – the presence of foreign body (paint, dirt, gap) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Material type – the best choice is pure iron steel. Stainless steels may attract less.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
Precautions when working with neodymium magnets
Respect the power
Handle magnets consciously. Their powerful strength can shock even professionals. Plan your moves and do not underestimate their force.
Magnet fragility
Neodymium magnets are sintered ceramics, which means they are fragile like glass. Clashing of two magnets will cause them breaking into small pieces.
Dust explosion hazard
Dust generated during machining of magnets is self-igniting. Do not drill into magnets without proper cooling and knowledge.
Swallowing risk
Product intended for adults. Small elements can be swallowed, causing intestinal necrosis. Store out of reach of kids and pets.
Nickel allergy
It is widely known that the nickel plating (standard magnet coating) is a common allergen. If you have an allergy, avoid touching magnets with bare hands or opt for coated magnets.
Magnetic media
Do not bring magnets near a purse, laptop, or TV. The magnetism can permanently damage these devices and erase data from cards.
Pacemakers
For implant holders: Strong magnetic fields disrupt medical devices. Maintain at least 30 cm distance or ask another person to work with the magnets.
Serious injuries
Danger of trauma: The pulling power is so immense that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.
Permanent damage
Control the heat. Heating the magnet above 80 degrees Celsius will ruin its properties and strength.
GPS and phone interference
Be aware: rare earth magnets generate a field that disrupts sensitive sensors. Keep a separation from your phone, tablet, and GPS.
