Pros and cons of rare earth magnets.
Pros
- They do not lose strength, even over approximately ten years – the drop in strength is only ~1% (based on measurements),
- Neodymium magnets are remarkably resistant to magnetic field loss caused by external field sources,
- The use of an metallic finish of noble metals (nickel, gold, silver) causes the element to look better,
- The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- In view of the option of free forming and customization to individualized needs, NdFeB magnets can be manufactured in a variety of shapes and sizes, which makes them more universal,
- Wide application in high-tech industry – they serve a role in HDD drives, drive modules, precision medical tools, as well as technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in small systems
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend a housing - magnetic mechanism, due to difficulties in creating threads inside the magnet and complicated forms.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these devices can be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Best holding force of the magnet in ideal parameters – what contributes to it?
- on a base made of mild steel, effectively closing the magnetic flux
- possessing a thickness of minimum 10 mm to avoid saturation
- with a surface cleaned and smooth
- without the slightest clearance between the magnet and steel
- during pulling in a direction vertical to the mounting surface
- at temperature approx. 20 degrees Celsius
Impact of factors on magnetic holding capacity in practice
- Space between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Plate thickness – insufficiently thick plate causes magnetic saturation, causing part of the flux to be wasted into the air.
- Steel type – low-carbon steel attracts best. Alloy steels decrease magnetic properties and lifting capacity.
- Base smoothness – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal environment – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Precautions when working with NdFeB magnets
Machining danger
Mechanical processing of neodymium magnets poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Allergy Warning
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If redness occurs, cease working with magnets and wear gloves.
Health Danger
People with a pacemaker have to maintain an safe separation from magnets. The magnetism can disrupt the operation of the implant.
Physical harm
Danger of trauma: The pulling power is so great that it can result in blood blisters, pinching, and broken bones. Use thick gloves.
Safe distance
Avoid bringing magnets near a purse, computer, or TV. The magnetism can destroy these devices and wipe information from cards.
Fragile material
Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Permanent damage
Standard neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.
Precision electronics
Note: rare earth magnets generate a field that confuses sensitive sensors. Maintain a separation from your phone, device, and navigation systems.
Do not underestimate power
Be careful. Rare earth magnets attract from a distance and connect with massive power, often faster than you can react.
Choking Hazard
Product intended for adults. Tiny parts can be swallowed, leading to intestinal necrosis. Keep out of reach of children and animals.
