Strengths and weaknesses of Nd2Fe14B magnets.
Benefits
- They do not lose strength, even over approximately 10 years – the decrease in strength is only ~1% (based on measurements),
- They possess excellent resistance to magnetism drop as a result of external fields,
- In other words, due to the reflective surface of silver, the element looks attractive,
- Neodymium magnets generate maximum magnetic induction on a their surface, which ensures high operational effectiveness,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures reaching 230°C and above...
- Thanks to versatility in shaping and the ability to adapt to client solutions,
- Universal use in innovative solutions – they serve a role in magnetic memories, brushless drives, advanced medical instruments, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in miniature devices
Limitations
- At strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of making threads in the magnet and complex forms - preferred is cover - mounting mechanism.
- Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. Additionally, small elements of these devices can be problematic in diagnostics medical in case of swallowing.
- With large orders the cost of neodymium magnets is a challenge,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what it depends on?
- with the application of a sheet made of low-carbon steel, ensuring maximum field concentration
- whose transverse dimension equals approx. 10 mm
- characterized by lack of roughness
- under conditions of no distance (surface-to-surface)
- during pulling in a direction vertical to the mounting surface
- at room temperature
Magnet lifting force in use – key factors
- Distance – the presence of foreign body (rust, dirt, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Direction of force – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Chemical composition of the base – mild steel gives the best results. Alloy admixtures decrease magnetic properties and holding force.
- Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
- Temperature influence – hot environment weakens pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity was measured by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet and the plate lowers the load capacity.
Safe handling of neodymium magnets
Do not underestimate power
Exercise caution. Rare earth magnets attract from a long distance and snap with massive power, often faster than you can move away.
Maximum temperature
Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. The loss of strength is permanent.
Hand protection
Watch your fingers. Two large magnets will snap together immediately with a force of massive weight, crushing everything in their path. Be careful!
Life threat
For implant holders: Powerful magnets disrupt medical devices. Maintain at least 30 cm distance or ask another person to work with the magnets.
Machining danger
Drilling and cutting of neodymium magnets carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Product not for children
Product intended for adults. Small elements pose a choking risk, causing intestinal necrosis. Keep away from children and animals.
Impact on smartphones
Navigation devices and mobile phones are highly sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Metal Allergy
It is widely known that the nickel plating (standard magnet coating) is a common allergen. If your skin reacts to metals, refrain from direct skin contact or select coated magnets.
Electronic hazard
Do not bring magnets near a wallet, laptop, or screen. The magnetism can destroy these devices and erase data from cards.
Material brittleness
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
