Pros as well as cons of rare earth magnets.
Strengths
- They do not lose strength, even over nearly ten years – the decrease in power is only ~1% (theoretically),
- Neodymium magnets remain extremely resistant to demagnetization caused by external interference,
- In other words, due to the shiny surface of silver, the element gains visual value,
- The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Considering the possibility of precise molding and adaptation to custom needs, magnetic components can be created in a wide range of shapes and sizes, which increases their versatility,
- Significant place in modern industrial fields – they are used in magnetic memories, drive modules, diagnostic systems, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in miniature devices
Weaknesses
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in realizing threads and complex forms in magnets, we propose using cover - magnetic mechanism.
- Health risk to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. It is also worth noting that small components of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum lifting force for a neodymium magnet – what it depends on?
- with the use of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- whose thickness equals approx. 10 mm
- characterized by lack of roughness
- with zero gap (no impurities)
- under axial force vector (90-degree angle)
- at conditions approx. 20°C
Determinants of practical lifting force of a magnet
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Load vector – maximum parameter is available only during perpendicular pulling. The resistance to sliding of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Material composition – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
- Thermal environment – temperature increase results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.
H&S for magnets
Electronic devices
Do not bring magnets near a purse, laptop, or screen. The magnetic field can destroy these devices and erase data from cards.
Conscious usage
Be careful. Neodymium magnets act from a long distance and snap with huge force, often faster than you can react.
Threat to navigation
Note: neodymium magnets generate a field that confuses sensitive sensors. Maintain a safe distance from your phone, device, and GPS.
Adults only
Product intended for adults. Tiny parts pose a choking risk, causing severe trauma. Keep away from kids and pets.
Physical harm
Danger of trauma: The pulling power is so immense that it can cause blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
Shattering risk
Beware of splinters. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Wear goggles.
Life threat
For implant holders: Strong magnetic fields disrupt electronics. Maintain at least 30 cm distance or request help to work with the magnets.
Heat warning
Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
Fire warning
Machining of NdFeB material poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Metal Allergy
Certain individuals suffer from a sensitization to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching can result in skin redness. It is best to wear safety gloves.
