Advantages as well as disadvantages of neodymium magnets.
Benefits
- They have constant strength, and over nearly ten years their performance decreases symbolically – ~1% (in testing),
- Magnets effectively resist against demagnetization caused by external fields,
- In other words, due to the reflective surface of nickel, the element gains a professional look,
- Magnets have impressive magnetic induction on the working surface,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Thanks to freedom in shaping and the ability to modify to individual projects,
- Huge importance in advanced technology sectors – they serve a role in computer drives, drive modules, diagnostic systems, as well as complex engineering applications.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Weaknesses
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing threads and complicated shapes in magnets, we propose using casing - magnetic mount.
- Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products can disrupt the diagnostic process medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is a challenge,
Pull force analysis
Maximum holding power of the magnet – what it depends on?
- using a base made of mild steel, serving as a magnetic yoke
- possessing a thickness of at least 10 mm to avoid saturation
- with a surface cleaned and smooth
- without the slightest air gap between the magnet and steel
- under perpendicular force direction (90-degree angle)
- at room temperature
Determinants of practical lifting force of a magnet
- Distance – existence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Load vector – highest force is reached only during pulling at a 90° angle. The shear force of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Chemical composition of the base – low-carbon steel attracts best. Alloy steels decrease magnetic permeability and holding force.
- Surface structure – the more even the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Thermal environment – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
Safe handling of NdFeB magnets
Product not for children
Only for adults. Tiny parts can be swallowed, causing severe trauma. Keep out of reach of children and animals.
Heat sensitivity
Monitor thermal conditions. Heating the magnet to high heat will permanently weaken its magnetic structure and pulling force.
Fire warning
Mechanical processing of neodymium magnets poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Sensitization to coating
Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. For allergy sufferers, refrain from direct skin contact or select coated magnets.
Do not underestimate power
Exercise caution. Rare earth magnets act from a distance and snap with massive power, often quicker than you can move away.
Data carriers
Powerful magnetic fields can erase data on credit cards, HDDs, and storage devices. Maintain a gap of at least 10 cm.
Physical harm
Mind your fingers. Two powerful magnets will join instantly with a force of massive weight, destroying anything in their path. Be careful!
ICD Warning
For implant holders: Powerful magnets affect medical devices. Keep minimum 30 cm distance or request help to handle the magnets.
Keep away from electronics
A strong magnetic field negatively affects the functioning of compasses in smartphones and GPS navigation. Do not bring magnets close to a smartphone to avoid breaking the sensors.
Material brittleness
Despite the nickel coating, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
