Strengths and weaknesses of Nd2Fe14B magnets.
Strengths
- They have unchanged lifting capacity, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
- They show high resistance to demagnetization induced by external field influence,
- Thanks to the smooth finish, the plating of Ni-Cu-Ni, gold, or silver-plated gives an elegant appearance,
- They feature high magnetic induction at the operating surface, which increases their power,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Thanks to versatility in designing and the ability to adapt to client solutions,
- Fundamental importance in modern industrial fields – they are utilized in mass storage devices, brushless drives, advanced medical instruments, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in miniature devices
Weaknesses
- To avoid cracks under impact, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- Neodymium magnets lose 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 stability even at temperatures up to 230°C
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of creating threads in the magnet and complicated forms - recommended is cover - magnetic holder.
- Potential hazard resulting from small fragments of magnets are risky, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small elements of these magnets can be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Maximum magnetic pulling force – what it depends on?
- with the application of a sheet made of special test steel, guaranteeing full magnetic saturation
- possessing a massiveness of at least 10 mm to ensure full flux closure
- characterized by lack of roughness
- with zero gap (no impurities)
- under perpendicular force vector (90-degree angle)
- at room temperature
Practical aspects of lifting capacity – factors
- Distance (between the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Steel type – low-carbon steel attracts best. Alloy admixtures lower magnetic properties and lifting capacity.
- Surface finish – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was measured by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
Safety rules for work with NdFeB magnets
Product not for children
Strictly keep magnets away from children. Choking hazard is significant, and the effects of magnets clamping inside the body are life-threatening.
Precision electronics
A powerful magnetic field disrupts the operation of magnetometers in smartphones and GPS navigation. Do not bring magnets close to a smartphone to avoid breaking the sensors.
Thermal limits
Regular neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Keep away from computers
Powerful magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Stay away of min. 10 cm.
Do not underestimate power
Handle magnets with awareness. Their powerful strength can shock even experienced users. Stay alert and do not underestimate their power.
Protective goggles
Neodymium magnets are sintered ceramics, meaning they are very brittle. Clashing of two magnets will cause them shattering into small pieces.
Crushing force
Pinching hazard: The attraction force is so immense that it can cause blood blisters, pinching, and even bone fractures. Use thick gloves.
Health Danger
Life threat: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Flammability
Powder created during machining of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Nickel coating and allergies
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If redness appears, cease working with magnets and wear gloves.
