Advantages as well as disadvantages of Nd2Fe14B magnets.
Advantages
- Their power is maintained, and after approximately ten years it decreases only by ~1% (theoretically),
- Magnets effectively resist against demagnetization caused by foreign field sources,
- The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to look better,
- Neodymium magnets deliver maximum magnetic induction on a contact point, which allows for strong attraction,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures reaching 230°C and above...
- Thanks to freedom in forming and the ability to modify to complex applications,
- Key role in electronics industry – they are used in magnetic memories, drive modules, diagnostic systems, also complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- At strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- We recommend cover - magnetic mount, due to difficulties in producing threads inside the magnet and complicated shapes.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these magnets are able to be problematic in diagnostics medical when they are in the body.
- With mass production the cost of neodymium magnets can be a barrier,
Holding force characteristics
Maximum magnetic pulling force – what it depends on?
- using a sheet made of low-carbon steel, functioning as a circuit closing element
- whose transverse dimension equals approx. 10 mm
- with an ideally smooth touching surface
- under conditions of no distance (surface-to-surface)
- during detachment in a direction vertical to the plane
- at ambient temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Steel grade – the best choice is pure iron steel. Cast iron may attract less.
- Base smoothness – the more even the surface, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Thermal environment – heating the magnet causes a temporary drop of induction. Check the thermal limit for a given model.
Lifting capacity was assessed by applying a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet and the plate lowers the holding force.
Warnings
Bone fractures
Pinching hazard: The pulling power is so immense that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.
Caution required
Handle with care. Rare earth magnets act from a distance and connect with huge force, often faster than you can move away.
Product not for children
Strictly store magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are life-threatening.
Machining danger
Dust produced during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Health Danger
For implant holders: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or ask another person to handle the magnets.
Threat to electronics
Avoid bringing magnets close to a purse, laptop, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Threat to navigation
Navigation devices and mobile phones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Protective goggles
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Power loss in heat
Avoid heat. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).
Metal Allergy
Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness happens, cease working with magnets and wear gloves.
