Strengths as well as weaknesses of Nd2Fe14B magnets.
Benefits
- Their strength is maintained, and after approximately 10 years it decreases only by ~1% (theoretically),
- They maintain their magnetic properties even under strong external field,
- In other words, due to the aesthetic surface of gold, the element looks attractive,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to modularity in designing and the capacity to adapt to complex applications,
- Key role in modern industrial fields – they are used in mass storage devices, electric drive systems, medical equipment, as well as other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We recommend cover - magnetic mount, due to difficulties in creating threads inside the magnet and complicated shapes.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. Additionally, small elements of these devices can complicate diagnosis medical when they are in the body.
- Due to complex production process, their price exceeds standard values,
Pull force analysis
Maximum holding power of the magnet – what contributes to it?
- on a block made of structural steel, perfectly concentrating the magnetic flux
- with a cross-section no less than 10 mm
- with a plane free of scratches
- under conditions of gap-free contact (metal-to-metal)
- under axial force direction (90-degree angle)
- at temperature approx. 20 degrees Celsius
Practical aspects of lifting capacity – factors
- Gap between surfaces – every millimeter of separation (caused e.g. by veneer or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Steel type – low-carbon steel attracts best. Alloy steels reduce magnetic properties and lifting capacity.
- Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
- Temperature – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
H&S for magnets
Medical implants
Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have medical devices.
Crushing risk
Danger of trauma: The attraction force is so immense that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.
Adults only
Always store magnets out of reach of children. Risk of swallowing is high, and the effects of magnets clamping inside the body are life-threatening.
Nickel coating and allergies
A percentage of the population experience a contact allergy to nickel, which is the typical protective layer for NdFeB magnets. Prolonged contact can result in an allergic reaction. We recommend use protective gloves.
Keep away from electronics
A powerful magnetic field negatively affects the functioning of magnetometers in phones and navigation systems. Maintain magnets close to a device to avoid breaking the sensors.
Safe operation
Use magnets with awareness. Their immense force can shock even experienced users. Stay alert and do not underestimate their power.
Magnets are brittle
NdFeB magnets are sintered ceramics, which means they are fragile like glass. Impact of two magnets will cause them breaking into shards.
Demagnetization risk
Do not overheat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, inquire about HT versions (H, SH, UH).
Cards and drives
Do not bring magnets near a wallet, laptop, or screen. The magnetism can permanently damage these devices and erase data from cards.
Machining danger
Mechanical processing of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
