Advantages and disadvantages of neodymium magnets.
Strengths
- They retain magnetic properties for nearly ten years – the loss is just ~1% (in theory),
- Neodymium magnets are characterized by remarkably resistant to demagnetization caused by external magnetic fields,
- By using a shiny coating of gold, the element has an modern look,
- Magnetic induction on the working layer of the magnet turns out to be exceptional,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures approaching 230°C and above...
- Thanks to versatility in shaping and the capacity to customize to specific needs,
- Wide application in future technologies – they find application in HDD drives, electric motors, medical equipment, and industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Weaknesses
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. 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 advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of making threads in the magnet and complicated shapes - recommended is a housing - magnetic holder.
- Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that small components of these devices are able to complicate diagnosis medical when they are in the body.
- Due to expensive raw materials, their price is relatively high,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what contributes to it?
- with the use of a sheet made of low-carbon steel, ensuring full magnetic saturation
- possessing a massiveness of at least 10 mm to avoid saturation
- characterized by even structure
- under conditions of gap-free contact (metal-to-metal)
- under axial force direction (90-degree angle)
- in neutral thermal conditions
Magnet lifting force in use – key factors
- Distance – existence of any layer (paint, tape, gap) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Steel thickness – too thin sheet does not close the flux, causing part of the flux to be lost into the air.
- Steel type – mild steel attracts best. Higher carbon content lower magnetic permeability and lifting capacity.
- Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet and the plate decreases the lifting capacity.
Safe handling of NdFeB magnets
Allergy Warning
It is widely known that the nickel plating (the usual finish) is a strong allergen. For allergy sufferers, prevent touching magnets with bare hands and choose encased magnets.
Permanent damage
Avoid heat. NdFeB magnets are susceptible to heat. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Swallowing risk
Product intended for adults. Small elements can be swallowed, causing severe trauma. Store away from children and animals.
Protect data
Do not bring magnets near a wallet, computer, or TV. The magnetism can permanently damage these devices and wipe information from cards.
Implant safety
For implant holders: Strong magnetic fields disrupt medical devices. Maintain minimum 30 cm distance or ask another person to work with the magnets.
Crushing force
Danger of trauma: The attraction force is so great that it can cause blood blisters, crushing, and broken bones. Use thick gloves.
Caution required
Use magnets consciously. Their huge power can shock even professionals. Be vigilant and do not underestimate their force.
Protective goggles
Despite metallic appearance, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.
Dust is flammable
Fire hazard: Neodymium dust is explosive. Do not process magnets without safety gear as this risks ignition.
Magnetic interference
Note: rare earth magnets generate a field that disrupts precision electronics. Keep a separation from your mobile, tablet, and GPS.
