Strengths as well as weaknesses of neodymium magnets.
Advantages
- Their magnetic field remains stable, and after around 10 years it decreases only by ~1% (according to research),
- They do not lose their magnetic properties even under close interference source,
- By using a reflective coating of nickel, the element gains an elegant look,
- Magnetic induction on the working part of the magnet turns out to be exceptional,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to freedom in shaping and the ability to customize to client solutions,
- Huge importance in advanced technology sectors – they are utilized in mass storage devices, motor assemblies, medical devices, as well as modern systems.
- Thanks to concentrated force, 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 securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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 very resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Limited possibility of making threads in the magnet and complex forms - recommended is cover - magnetic holder.
- Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. Additionally, small components of these products can disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Magnetic strength at its maximum – what contributes to it?
- on a base made of mild steel, effectively closing the magnetic flux
- possessing a thickness of minimum 10 mm to avoid saturation
- with a surface free of scratches
- under conditions of gap-free contact (surface-to-surface)
- during pulling in a direction perpendicular to the mounting surface
- in temp. approx. 20°C
Determinants of practical lifting force of a magnet
- Clearance – the presence of any layer (paint, dirt, air) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Steel type – low-carbon steel gives the best results. Higher carbon content lower magnetic permeability and holding force.
- Smoothness – full contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
- Thermal factor – high temperature reduces magnetic field. Too high temperature can permanently damage the magnet.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Do not give to children
Absolutely store magnets away from children. Ingestion danger is significant, and the effects of magnets clamping inside the body are very dangerous.
Threat to navigation
Be aware: rare earth magnets generate a field that interferes with sensitive sensors. Maintain a separation from your phone, device, and GPS.
Operating temperature
Watch the temperature. Exposing the magnet to high heat will destroy its properties and strength.
Do not underestimate power
Handle magnets with awareness. Their huge power can surprise even experienced users. Plan your moves and do not underestimate their power.
Risk of cracking
Despite the nickel coating, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
ICD Warning
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Fire warning
Fire hazard: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.
Bodily injuries
Watch your fingers. Two large magnets will join instantly with a force of massive weight, crushing everything in their path. Be careful!
Safe distance
Device Safety: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, medical aids, timepieces).
Warning for allergy sufferers
Studies show that nickel (standard magnet coating) is a potent allergen. If you have an allergy, refrain from direct skin contact and select coated magnets.
