Pros as well as cons of rare earth magnets.
Advantages
- They have constant strength, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
- Neodymium magnets are extremely resistant to demagnetization caused by external magnetic fields,
- In other words, due to the metallic layer of gold, the element becomes visually attractive,
- Neodymium magnets achieve maximum magnetic induction on a small area, which allows for strong attraction,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to modularity in forming and the ability to adapt to complex applications,
- Versatile presence in high-tech industry – they serve a role in data components, brushless drives, precision medical tools, and multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Disadvantages
- At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited ability of making nuts in the magnet and complicated shapes - recommended is cover - mounting mechanism.
- Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. Furthermore, tiny parts of these devices can be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Magnetic strength at its maximum – what it depends on?
- with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
- whose transverse dimension reaches at least 10 mm
- characterized by even structure
- without the slightest air gap between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- in neutral thermal conditions
What influences lifting capacity in practice
- Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds much less (often approx. 20-30% of maximum force).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Metal type – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
- Base smoothness – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Temperature influence – hot environment reduces pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity was determined with the use of a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the holding force is lower. Additionally, even a small distance between the magnet and the plate lowers the lifting capacity.
Warnings
Danger to pacemakers
Warning for patients: Powerful magnets affect electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.
Skin irritation risks
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If redness happens, cease working with magnets and wear gloves.
Eye protection
Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Thermal limits
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and strength.
Fire warning
Combustion risk: Rare earth powder is highly flammable. Do not process magnets without safety gear as this risks ignition.
Bodily injuries
Risk of injury: The attraction force is so great that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
Conscious usage
Exercise caution. Rare earth magnets attract from a distance and connect with huge force, often quicker than you can move away.
Choking Hazard
These products are not intended for children. Eating a few magnets can lead to them pinching intestinal walls, which poses a severe health hazard and necessitates urgent medical intervention.
Impact on smartphones
Note: rare earth magnets generate a field that interferes with precision electronics. Keep a separation from your mobile, tablet, and navigation systems.
Safe distance
Intense magnetic fields can erase data on credit cards, hard drives, and storage devices. Maintain a gap of min. 10 cm.
