Strengths as well as weaknesses of rare earth magnets.
Strengths
- Their power is durable, and after approximately ten years it drops only by ~1% (according to research),
- Neodymium magnets are remarkably resistant to loss of magnetic properties caused by magnetic disturbances,
- In other words, due to the aesthetic surface of nickel, the element gains a professional look,
- Neodymium magnets achieve maximum magnetic induction on a small surface, which ensures high operational effectiveness,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to modularity in constructing and the ability to adapt to complex applications,
- Huge importance in high-tech industry – they find application in data components, brushless drives, precision medical tools, as well as complex engineering applications.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Limitations
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and 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
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic holder, due to difficulties in creating nuts inside the magnet and complex shapes.
- Possible danger to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these devices are able to disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- on a block made of mild steel, effectively closing the magnetic field
- with a cross-section no less than 10 mm
- characterized by smoothness
- without any air gap between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at room temperature
Determinants of lifting force in real conditions
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Load vector – maximum parameter is reached only during pulling at a 90° angle. The force required to slide of the magnet along the surface is standardly several times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Material type – the best choice is high-permeability steel. Cast iron may attract less.
- Surface condition – ground elements guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
- Thermal factor – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
H&S for magnets
Do not give to children
Only for adults. Small elements pose a choking risk, leading to severe trauma. Store out of reach of children and animals.
Threat to navigation
Be aware: rare earth magnets generate a field that disrupts sensitive sensors. Maintain a separation from your phone, tablet, and GPS.
Eye protection
NdFeB magnets are ceramic materials, which means they are prone to chipping. Collision of two magnets will cause them breaking into small pieces.
Electronic devices
Very strong magnetic fields can erase data on payment cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
Allergy Warning
Studies show that the nickel plating (the usual finish) is a strong allergen. If your skin reacts to metals, prevent direct skin contact or choose encased magnets.
Crushing force
Mind your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
Implant safety
For implant holders: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or request help to work with the magnets.
Fire risk
Drilling and cutting of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Heat warning
Control the heat. Heating the magnet to high heat will permanently weaken its magnetic structure and pulling force.
Do not underestimate power
Be careful. Neodymium magnets attract from a long distance and connect with huge force, often faster than you can move away.
