Strengths as well as weaknesses of Nd2Fe14B magnets.
Strengths
- They have unchanged lifting capacity, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
- They maintain their magnetic properties even under strong external field,
- A magnet with a shiny gold surface has an effective appearance,
- Magnetic induction on the surface of the magnet is very high,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures reaching 230°C and above...
- Thanks to freedom in forming and the ability to modify to individual projects,
- Fundamental importance in future technologies – they are utilized in computer drives, electric motors, medical devices, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in small systems
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. 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, in case of application outdoors
- We suggest casing - magnetic holder, due to difficulties in creating nuts inside the magnet and complex forms.
- Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the context of child safety. Furthermore, small elements of these devices are able to be problematic in diagnostics medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what it depends on?
- on a plate made of structural steel, perfectly concentrating the magnetic flux
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with an polished touching surface
- with direct contact (without paint)
- for force acting at a right angle (pull-off, not shear)
- in neutral thermal conditions
Determinants of practical lifting force of a magnet
- Space between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Steel thickness – too thin sheet causes magnetic saturation, causing part of the flux to be wasted into the air.
- Metal type – different alloys reacts the same. High carbon content worsen the attraction effect.
- Surface quality – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was measured by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
Safe handling of neodymium magnets
Caution required
Be careful. Rare earth magnets attract from a distance and connect with massive power, often faster than you can react.
Eye protection
Despite the nickel coating, the material is delicate and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.
Physical harm
Watch your fingers. Two powerful magnets will join instantly with a force of massive weight, crushing everything in their path. Exercise extreme caution!
Fire risk
Fire hazard: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.
Keep away from electronics
Note: neodymium magnets generate a field that confuses sensitive sensors. Keep a separation from your mobile, tablet, and navigation systems.
Demagnetization risk
Standard neodymium magnets (N-type) lose power when the temperature surpasses 80°C. The loss of strength is permanent.
Medical interference
Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Avoid contact if allergic
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, cease handling magnets and wear gloves.
Safe distance
Intense magnetic fields can erase data on payment cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Choking Hazard
Neodymium magnets are not intended for children. Swallowing a few magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and requires immediate surgery.
