Pros as well as cons of neodymium magnets.
Strengths
- They have constant strength, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
- Neodymium magnets are highly resistant to loss of magnetic properties caused by external field sources,
- The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnets possess excellent magnetic induction on the active area,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Possibility of precise creating and adapting to defined conditions,
- Significant place in innovative solutions – they serve a role in magnetic memories, electric drive systems, advanced medical instruments, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in small systems
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- Neodymium magnets decrease their strength 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 rust. Therefore during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We recommend a housing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complicated shapes.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key 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
Lifting parameters
Maximum lifting capacity of the magnet – what it depends on?
- with the use of a sheet made of special test steel, guaranteeing full magnetic saturation
- possessing a thickness of at least 10 mm to ensure full flux closure
- with a plane cleaned and smooth
- without the slightest clearance between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- in temp. approx. 20°C
Determinants of practical lifting force of a magnet
- Distance (between the magnet and the metal), because even a tiny distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Chemical composition of the base – low-carbon steel gives the best results. Alloy steels decrease magnetic permeability and lifting capacity.
- Smoothness – full contact is possible only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Thermal factor – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was measured with the use of a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.
Warnings
Bodily injuries
Big blocks can crush fingers in a fraction of a second. Under no circumstances place your hand betwixt two attracting surfaces.
Fire risk
Powder produced during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.
Keep away from electronics
Navigation devices and mobile phones are extremely sensitive to magnetic fields. Close proximity with a strong magnet can ruin the sensors in your phone.
Threat to electronics
Do not bring magnets close to a purse, laptop, or TV. The magnetism can destroy these devices and wipe information from cards.
Beware of splinters
Watch out for shards. Magnets can fracture upon violent connection, ejecting shards into the air. We recommend safety glasses.
ICD Warning
Health Alert: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Choking Hazard
NdFeB magnets are not suitable for play. Accidental ingestion of a few magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and necessitates urgent medical intervention.
Caution required
Exercise caution. Neodymium magnets act from a distance and connect with massive power, often quicker than you can react.
Allergy Warning
Studies show that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, avoid direct skin contact or choose encased magnets.
Operating temperature
Watch the temperature. Heating the magnet to high heat will destroy its magnetic structure and pulling force.
