Advantages and disadvantages of neodymium magnets.
Strengths
- Their power is durable, and after around 10 years it decreases only by ~1% (according to research),
- Magnets very well resist against demagnetization caused by foreign field sources,
- By applying a smooth layer of silver, the element acquires an aesthetic look,
- Magnetic induction on the top side of the magnet is impressive,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures approaching 230°C and above...
- Considering the possibility of free forming and customization to unique solutions, magnetic components can be produced in a variety of forms and dimensions, which expands the range of possible applications,
- Significant place in modern technologies – they are commonly used in hard drives, motor assemblies, medical equipment, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which makes them useful in compact constructions
Disadvantages
- 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 increases its resistance to damage
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We suggest cover - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated forms.
- Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that small components of these products are able to be problematic in diagnostics medical in case of swallowing.
- With budget limitations the cost of neodymium magnets can be a barrier,
Pull force analysis
Detachment force of the magnet in optimal conditions – what contributes to it?
- on a plate made of mild steel, optimally conducting the magnetic field
- possessing a massiveness of min. 10 mm to ensure full flux closure
- characterized by smoothness
- without the slightest air gap between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at conditions approx. 20°C
Determinants of practical lifting force of a magnet
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Material type – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined using a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
Safe handling of NdFeB magnets
Life threat
Warning for patients: Strong magnetic fields affect electronics. Keep at least 30 cm distance or ask another person to handle the magnets.
Do not underestimate power
Handle with care. Neodymium magnets act from a distance and connect with massive power, often faster than you can react.
Phone sensors
Be aware: rare earth magnets generate a field that disrupts precision electronics. Keep a safe distance from your phone, device, and navigation systems.
Product not for children
NdFeB magnets are not suitable for play. Swallowing a few magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and requires urgent medical intervention.
Combustion hazard
Powder produced during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Skin irritation risks
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If redness happens, cease working with magnets and wear gloves.
Demagnetization risk
Do not overheat. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).
Hand protection
Risk of injury: The attraction force is so immense that it can result in hematomas, pinching, and even bone fractures. Use thick gloves.
Threat to electronics
Intense magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
Eye protection
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
