Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- They have stable power, and over around ten years their attraction force decreases symbolically – ~1% (in testing),
- They retain their magnetic properties even under external field action,
- By using a shiny coating of silver, the element has an proper look,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures reaching 230°C and above...
- Possibility of custom forming as well as optimizing to specific needs,
- Versatile presence in modern technologies – they are used in HDD drives, drive modules, medical devices, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in compact constructions
Limitations
- At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of producing nuts in the magnet and complicated forms - recommended is casing - mounting mechanism.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these devices can be problematic in diagnostics medical after entering the body.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- whose thickness is min. 10 mm
- with a surface free of scratches
- under conditions of gap-free contact (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Steel thickness – insufficiently thick plate does not accept the full field, causing part of the power to be lost into the air.
- Chemical composition of the base – mild steel gives the best results. Alloy steels reduce magnetic permeability and lifting capacity.
- Surface quality – the more even the surface, the better the adhesion and stronger the hold. Unevenness creates an air distance.
- Temperature – temperature increase causes a temporary drop of force. Check the maximum operating temperature for a given model.
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under shearing force the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate lowers the load capacity.
Precautions when working with NdFeB magnets
Precision electronics
Note: rare earth magnets produce a field that disrupts precision electronics. Maintain a separation from your mobile, device, and navigation systems.
Do not overheat magnets
Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Shattering risk
Beware of splinters. Magnets can fracture upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.
Keep away from children
Product intended for adults. Tiny parts can be swallowed, causing severe trauma. Keep out of reach of children and animals.
Mechanical processing
Mechanical processing of neodymium magnets carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Skin irritation risks
Certain individuals suffer from a contact allergy to nickel, which is the common plating for NdFeB magnets. Frequent touching may cause an allergic reaction. It is best to wear safety gloves.
Crushing force
Big blocks can smash fingers instantly. Never put your hand between two strong magnets.
ICD Warning
Life threat: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Immense force
Exercise caution. Neodymium magnets act from a long distance and connect with huge force, often quicker than you can react.
Protect data
Powerful magnetic fields can corrupt files on payment cards, hard drives, and storage devices. Stay away of min. 10 cm.
