Strengths as well as weaknesses of neodymium magnets.
Strengths
- Their magnetic field is maintained, and after approximately 10 years it decreases only by ~1% (according to research),
- They have excellent resistance to magnetic field loss due to external fields,
- A magnet with a smooth silver surface is more attractive,
- Neodymium magnets ensure maximum magnetic induction on a contact point, which increases force concentration,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
- In view of the potential of precise shaping and customization to specialized needs, magnetic components can be manufactured in a variety of shapes and sizes, which makes them more universal,
- Huge importance in high-tech industry – they are used in magnetic memories, motor assemblies, medical devices, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in miniature devices
Weaknesses
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely 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 stable to moisture, in case of application outdoors
- We suggest a housing - magnetic holder, due to difficulties in creating nuts inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small components of these products can be problematic in diagnostics medical when they are in the body.
- Due to complex production process, their price exceeds standard values,
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- on a block made of structural steel, perfectly concentrating the magnetic flux
- whose thickness equals approx. 10 mm
- characterized by smoothness
- under conditions of no distance (metal-to-metal)
- under vertical force vector (90-degree angle)
- at conditions approx. 20°C
Determinants of practical lifting force of a magnet
- Gap between surfaces – every millimeter of separation (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (typically approx. 20-30% of nominal force).
- Plate thickness – too thin plate does not close the flux, causing part of the power to be wasted to the other side.
- Metal type – not every steel reacts the same. High carbon content worsen the attraction effect.
- Surface condition – ground elements guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was measured by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a small distance between the magnet’s surface and the plate reduces the holding force.
H&S for magnets
Powerful field
Use magnets with awareness. Their immense force can shock even experienced users. Plan your moves and do not underestimate their force.
Magnetic interference
Be aware: neodymium magnets generate a field that interferes with precision electronics. Keep a separation from your phone, device, and GPS.
Machining danger
Dust generated during cutting of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Risk of cracking
NdFeB magnets are ceramic materials, which means they are prone to chipping. Collision of two magnets leads to them shattering into shards.
Nickel allergy
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, immediately stop working with magnets and wear gloves.
Hand protection
Risk of injury: The pulling power is so immense that it can result in hematomas, pinching, and broken bones. Use thick gloves.
Life threat
Life threat: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Maximum temperature
Standard neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. The loss of strength is permanent.
Protect data
Device Safety: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, timepieces).
No play value
Strictly store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are fatal.
