Advantages as well as disadvantages of Nd2Fe14B magnets.
Advantages
- They retain full power for around 10 years – the loss is just ~1% (based on simulations),
- Magnets very well resist against demagnetization caused by foreign field sources,
- By using a shiny layer of silver, the element gains an nice look,
- The surface of neodymium magnets generates a maximum magnetic field – this is one of their assets,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Possibility of exact forming and modifying to atypical conditions,
- Fundamental importance in modern industrial fields – they are used in magnetic memories, drive modules, medical devices, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in miniature devices
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- We suggest casing - magnetic mount, due to difficulties in creating threads inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small elements of these products are able to disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Maximum magnetic pulling force – what it depends on?
- using a base made of low-carbon steel, serving as a ideal flux conductor
- with a thickness no less than 10 mm
- characterized by smoothness
- with total lack of distance (without impurities)
- during detachment in a direction perpendicular to the plane
- in temp. approx. 20°C
What influences lifting capacity in practice
- Air gap (betwixt the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Steel thickness – insufficiently thick steel does not accept the full field, causing part of the power to be escaped to the other side.
- Steel type – mild steel gives the best results. Alloy admixtures reduce magnetic properties and lifting capacity.
- Base smoothness – the smoother and more polished the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was measured with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
H&S for magnets
Permanent damage
Do not overheat. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Swallowing risk
These products are not suitable for play. Accidental ingestion of several magnets may result in them pinching intestinal walls, which constitutes a direct threat to life and necessitates urgent medical intervention.
Pinching danger
Risk of injury: The pulling power is so immense that it can result in hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Machining danger
Mechanical processing of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Shattering risk
Beware of splinters. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Wear goggles.
Handling rules
Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Data carriers
Do not bring magnets close to a purse, computer, or screen. The magnetic field can irreversibly ruin these devices and wipe information from cards.
Danger to pacemakers
Patients with a pacemaker have to keep an large gap from magnets. The magnetism can stop the operation of the life-saving device.
Phone sensors
Note: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your phone, tablet, and GPS.
Warning for allergy sufferers
It is widely known that nickel (standard magnet coating) is a strong allergen. If you have an allergy, avoid direct skin contact and opt for coated magnets.
