Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- They retain attractive force for almost 10 years – the drop is just ~1% (in theory),
- They are noted for resistance to demagnetization induced by external disturbances,
- By using a lustrous coating of nickel, the element has an proper look,
- Neodymium magnets ensure maximum magnetic induction on a small area, which allows for strong attraction,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures approaching 230°C and above...
- Thanks to versatility in constructing and the ability to adapt to unusual requirements,
- Universal use in high-tech industry – they are utilized in magnetic memories, drive modules, advanced medical instruments, as well as technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets lose their force 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 stability even at temperatures up to 230°C
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complex forms in magnets, we recommend using a housing - magnetic mount.
- Health risk resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, small elements of these devices are able to disrupt the diagnostic process medical when they are in the body.
- Due to neodymium price, their price exceeds standard values,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what affects it?
- using a base made of high-permeability steel, acting as a ideal flux conductor
- whose thickness reaches at least 10 mm
- characterized by smoothness
- with zero gap (no coatings)
- under axial application of breakaway force (90-degree angle)
- at temperature room level
Lifting capacity in practice – influencing factors
- Distance (between the magnet and the plate), as even a very small distance (e.g. 0.5 mm) leads to a reduction in force by up to 50% (this also applies to varnish, corrosion or debris).
- Load vector – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Chemical composition of the base – mild steel gives the best results. Alloy admixtures reduce magnetic permeability and holding force.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
- Thermal environment – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
Finger safety
Danger of trauma: The pulling power is so immense that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.
Beware of splinters
Protect your eyes. Magnets can fracture upon violent connection, launching sharp fragments into the air. Eye protection is mandatory.
Allergy Warning
Some people have a sensitization to nickel, which is the standard coating for NdFeB magnets. Frequent touching may cause dermatitis. We recommend wear protective gloves.
Magnetic media
Intense magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.
Combustion hazard
Drilling and cutting of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Product not for children
Neodymium magnets are not toys. Eating several magnets can lead to them attracting across intestines, which constitutes a critical condition and necessitates urgent medical intervention.
Implant safety
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Permanent damage
Keep cool. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, look for HT versions (H, SH, UH).
Handling rules
Before use, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.
GPS Danger
Be aware: neodymium magnets produce a field that confuses sensitive sensors. Maintain a separation from your phone, tablet, and navigation systems.
