Advantages as well as disadvantages of neodymium magnets.
Benefits
- They have stable power, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
- They are noted for resistance to demagnetization induced by external disturbances,
- Thanks to the shiny finish, the layer of nickel, gold, or silver-plated gives an clean appearance,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of precise shaping and adjusting to specific needs,
- Universal use in advanced technology sectors – they are used in mass storage devices, brushless drives, advanced medical instruments, as well as modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- 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 possibility of producing nuts in the magnet and complex shapes - recommended is a housing - mounting mechanism.
- Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that small elements of these products can complicate diagnosis medical in case of swallowing.
- Due to neodymium price, their price is relatively high,
Pull force analysis
Magnetic strength at its maximum – what contributes to it?
- with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- with a cross-section minimum 10 mm
- characterized by smoothness
- under conditions of ideal adhesion (metal-to-metal)
- during pulling in a direction vertical to the mounting surface
- at temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Space between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Steel thickness – too thin steel does not accept the full field, causing part of the flux to be escaped into the air.
- Metal type – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
- Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, however under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Pinching danger
Danger of trauma: The attraction force is so immense that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.
Combustion hazard
Machining of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Electronic devices
Intense magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.
Threat to navigation
A strong magnetic field negatively affects the operation of compasses in smartphones and navigation systems. Keep magnets close to a device to prevent breaking the sensors.
Powerful field
Handle magnets consciously. Their huge power can surprise even experienced users. Stay alert and respect their force.
Implant safety
For implant holders: Strong magnetic fields affect electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.
Fragile material
Neodymium magnets are ceramic materials, which means they are fragile like glass. Clashing of two magnets will cause them shattering into small pieces.
Operating temperature
Do not overheat. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Danger to the youngest
Product intended for adults. Small elements pose a choking risk, leading to severe trauma. Store out of reach of children and animals.
Nickel allergy
It is widely known that nickel (the usual finish) is a common allergen. For allergy sufferers, avoid direct skin contact or select versions in plastic housing.
