Advantages as well as disadvantages of Nd2Fe14B magnets.
Strengths
- They do not lose magnetism, even after approximately 10 years – the decrease in lifting capacity is only ~1% (based on measurements),
- They have excellent resistance to magnetic field loss when exposed to opposing magnetic fields,
- The use of an aesthetic coating of noble metals (nickel, gold, silver) causes the element to present itself better,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures reaching 230°C and above...
- Thanks to modularity in forming and the capacity to modify to client solutions,
- Significant place in advanced technology sectors – they are commonly used in mass storage devices, electromotive mechanisms, medical equipment, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in compact constructions
Weaknesses
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets lose their power 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 - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited possibility of creating threads in the magnet and complex shapes - preferred is casing - magnet mounting.
- Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that small components of these products are able to complicate diagnosis medical when they are in the body.
- Due to complex production process, their price exceeds standard values,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- with the use of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with an ground contact surface
- with zero gap (no paint)
- during detachment in a direction vertical to the plane
- at ambient temperature approx. 20 degrees Celsius
Practical lifting capacity: influencing factors
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Metal type – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
- Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Heat – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the load capacity is reduced by as much as 5 times. Moreover, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Do not drill into magnets
Powder generated during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Do not overheat magnets
Control the heat. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
Nickel coating and allergies
It is widely known that the nickel plating (the usual finish) is a potent allergen. For allergy sufferers, prevent touching magnets with bare hands and opt for encased magnets.
Keep away from children
Only for adults. Small elements can be swallowed, leading to intestinal necrosis. Keep out of reach of children and animals.
Bodily injuries
Big blocks can smash fingers instantly. Under no circumstances put your hand between two attracting surfaces.
Implant safety
Warning for patients: Powerful magnets affect electronics. Maintain at least 30 cm distance or request help to handle the magnets.
Risk of cracking
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Electronic devices
Data protection: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
Precision electronics
Be aware: neodymium magnets produce a field that interferes with precision electronics. Keep a separation from your phone, tablet, and navigation systems.
Immense force
Before use, check safety instructions. Sudden snapping can break the magnet or injure your hand. Be predictive.
