Advantages as well as disadvantages of neodymium magnets.
Advantages
- They do not lose strength, even after nearly ten years – the reduction in lifting capacity is only ~1% (theoretically),
- They show high resistance to demagnetization induced by external magnetic fields,
- In other words, due to the shiny finish of nickel, the element gains a professional look,
- Neodymium magnets create maximum magnetic induction on a small surface, which increases force concentration,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of precise machining as well as adjusting to specific conditions,
- Wide application in modern technologies – they are utilized in mass storage devices, electromotive mechanisms, diagnostic systems, as well as technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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 very resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- We suggest a housing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complex forms.
- Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that small components of these products can be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum lifting capacity of the magnet – what it depends on?
- using a sheet made of high-permeability steel, serving as a magnetic yoke
- possessing a thickness of at least 10 mm to ensure full flux closure
- with an ground touching surface
- without any air gap between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- in stable room temperature
Practical lifting capacity: influencing factors
- Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Material composition – different alloys attracts identically. High carbon content weaken the attraction effect.
- Surface quality – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a small distance between the magnet and the plate lowers the lifting capacity.
Precautions when working with NdFeB magnets
Heat warning
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
GPS Danger
An intense magnetic field negatively affects the functioning of magnetometers in phones and navigation systems. Maintain magnets near a device to avoid damaging the sensors.
Data carriers
Device Safety: Strong magnets can damage data carriers and sensitive devices (heart implants, hearing aids, mechanical watches).
Flammability
Fire warning: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.
Shattering risk
Neodymium magnets are sintered ceramics, which means they are fragile like glass. Clashing of two magnets leads to them breaking into small pieces.
Product not for children
Strictly keep magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are tragic.
Allergy Warning
Studies show that the nickel plating (the usual finish) is a strong allergen. If you have an allergy, refrain from touching magnets with bare hands and opt for encased magnets.
Immense force
Exercise caution. Rare earth magnets attract from a distance and connect with huge force, often faster than you can move away.
Medical implants
People with a pacemaker should maintain an large gap from magnets. The magnetism can stop the functioning of the implant.
Bodily injuries
Watch your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!
