Strengths and weaknesses of rare earth magnets.
Advantages
- They have unchanged lifting capacity, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
- Magnets effectively protect themselves against loss of magnetization caused by foreign field sources,
- The use of an refined coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a distinguishing feature,
- 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 capacity to adapt to unusual requirements,
- Wide application in future technologies – they are commonly used in mass storage devices, electric motors, diagnostic systems, as well as complex engineering applications.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We suggest cover - magnetic holder, due to difficulties in realizing threads inside the magnet and complex shapes.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. Additionally, small components of these magnets 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
Detachment force of the magnet in optimal conditions – what affects it?
- with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- possessing a thickness of min. 10 mm to avoid saturation
- characterized by smoothness
- with total lack of distance (without coatings)
- under perpendicular force vector (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Magnet lifting force in use – key factors
- Distance – existence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Plate material – mild steel gives the best results. Alloy admixtures lower magnetic permeability and lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
- Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
Precautions when working with neodymium magnets
Phone sensors
Note: rare earth magnets produce a field that disrupts sensitive sensors. Maintain a safe distance from your mobile, tablet, and navigation systems.
Life threat
Health Alert: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Product not for children
Always keep magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are life-threatening.
Serious injuries
Mind your fingers. Two large magnets will join immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Protect data
Equipment safety: Neodymium magnets can ruin payment cards and sensitive devices (pacemakers, medical aids, mechanical watches).
Dust explosion hazard
Dust created during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.
Sensitization to coating
Some people experience a sensitization to Ni, which is the typical protective layer for NdFeB magnets. Frequent touching may cause skin redness. It is best to use protective gloves.
Fragile material
Beware of splinters. Magnets can fracture upon violent connection, launching shards into the air. Eye protection is mandatory.
Thermal limits
Keep cool. NdFeB magnets are susceptible to heat. If you require operation above 80°C, inquire about HT versions (H, SH, UH).
Powerful field
Be careful. Rare earth magnets act from a long distance and connect with massive power, often faster than you can react.
