Pros and cons of Nd2Fe14B magnets.
Pros
- They retain full power for around ten years – the loss is just ~1% (based on simulations),
- Neodymium magnets are distinguished by extremely resistant to loss of magnetic properties caused by external field sources,
- Thanks to the smooth finish, the surface of nickel, gold-plated, or silver gives an aesthetic appearance,
- Magnets have huge magnetic induction on the active area,
- 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 accurate creating and adjusting to atypical applications,
- Universal use in innovative solutions – they find application in magnetic memories, brushless drives, medical devices, as well as multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Disadvantages
- To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets lose their strength 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 stability even at temperatures up to 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, when using outdoors
- We recommend cover - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated forms.
- Potential hazard related to microscopic parts of magnets pose a threat, 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 when they are in the body.
- Due to neodymium price, their price exceeds standard values,
Lifting parameters
Maximum magnetic pulling force – what affects it?
- using a plate made of mild steel, acting as a magnetic yoke
- whose transverse dimension is min. 10 mm
- with an ground contact surface
- under conditions of gap-free contact (surface-to-surface)
- under vertical force direction (90-degree angle)
- at temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Base massiveness – too thin sheet does not close the flux, causing part of the flux to be escaped to the other side.
- Steel type – mild steel attracts best. Higher carbon content lower magnetic properties and holding force.
- Surface structure – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was measured with the use of a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate decreases the holding force.
Warnings
Bone fractures
Big blocks can smash fingers in a fraction of a second. Under no circumstances place your hand betwixt two attracting surfaces.
Flammability
Combustion risk: Neodymium dust is explosive. Avoid machining magnets without safety gear as this risks ignition.
Warning for allergy sufferers
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If redness occurs, immediately stop handling magnets and use protective gear.
Thermal limits
Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
Threat to navigation
Remember: rare earth magnets generate a field that disrupts precision electronics. Keep a safe distance from your phone, device, and GPS.
Medical interference
People with a pacemaker must keep an safe separation from magnets. The magnetic field can interfere with the functioning of the implant.
Keep away from children
Product intended for adults. Tiny parts pose a choking risk, leading to severe trauma. Store out of reach of kids and pets.
Handling rules
Handle with care. Neodymium magnets attract from a long distance and snap with massive power, often quicker than you can move away.
Data carriers
Very strong magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Stay away of at least 10 cm.
Eye protection
NdFeB magnets are ceramic materials, which means they are very brittle. Collision of two magnets leads to them shattering into small pieces.
