Pros and cons of rare earth magnets.
Advantages
- They do not lose magnetism, even over approximately ten years – the drop in strength is only ~1% (based on measurements),
- Magnets perfectly protect themselves against demagnetization caused by foreign field sources,
- In other words, due to the shiny finish of nickel, the element becomes visually attractive,
- Neodymium magnets generate maximum magnetic induction on a their surface, which ensures high operational effectiveness,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures reaching 230°C and above...
- Thanks to modularity in constructing and the ability to customize to individual projects,
- Fundamental importance in modern industrial fields – they are utilized in computer drives, brushless drives, medical equipment, as well as modern systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Disadvantages
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of making threads in the magnet and complex shapes - preferred is a housing - magnet mounting.
- Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that small elements of these devices can disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum holding power of the magnet – what contributes to it?
- with the contact of a yoke made of special test steel, ensuring full magnetic saturation
- possessing a thickness of minimum 10 mm to ensure full flux closure
- with a plane free of scratches
- without any insulating layer between the magnet and steel
- during detachment in a direction perpendicular to the mounting surface
- in stable room temperature
Practical lifting capacity: influencing factors
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Direction of force – highest force is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick steel does not close the flux, causing part of the flux to be wasted to the other side.
- Metal type – different alloys reacts the same. Alloy additives weaken the attraction effect.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet and the plate decreases the holding force.
H&S for magnets
Allergy Warning
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness occurs, immediately stop handling magnets and wear gloves.
Data carriers
Intense magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.
Medical implants
Life threat: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
GPS and phone interference
GPS units and mobile phones are highly sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.
This is not a toy
Absolutely store magnets away from children. Choking hazard is significant, and the consequences of magnets clamping inside the body are life-threatening.
Heat warning
Do not overheat. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
Flammability
Mechanical processing of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Material brittleness
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets leads to them breaking into small pieces.
Caution required
Handle with care. Rare earth magnets attract from a distance and snap with massive power, often faster than you can move away.
Bodily injuries
Pinching hazard: The pulling power is so great that it can result in blood blisters, crushing, and even bone fractures. Use thick gloves.
