Strengths as well as weaknesses of neodymium magnets.
Benefits
- They retain attractive force for around ten years – the loss is just ~1% (according to analyses),
- They are resistant to demagnetization induced by external magnetic fields,
- A magnet with a metallic silver surface is more attractive,
- Neodymium magnets generate maximum magnetic induction on a small area, which ensures high operational effectiveness,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Considering the ability of precise shaping and adaptation to specialized solutions, magnetic components can be modeled in a variety of geometric configurations, which makes them more universal,
- Huge importance in modern technologies – they are used in magnetic memories, motor assemblies, advanced medical instruments, also technologically advanced constructions.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we recommend 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, in case of application outdoors
- We suggest cover - magnetic mount, due to difficulties in realizing 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 safety. It is also worth noting that small components of these products are able to complicate diagnosis medical when they are in the body.
- With large orders the cost of neodymium magnets is economically unviable,
Pull force analysis
Best holding force of the magnet in ideal parameters – what it depends on?
- with the application of a yoke made of low-carbon steel, ensuring maximum field concentration
- whose transverse dimension is min. 10 mm
- characterized by even structure
- without any clearance between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Material type – the best choice is high-permeability steel. Stainless steels may have worse magnetic properties.
- Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, however under parallel forces the holding force is lower. Additionally, even a slight gap between the magnet and the plate reduces the load capacity.
Safety rules for work with NdFeB magnets
Keep away from children
Absolutely store magnets out of reach of children. Ingestion danger is high, and the effects of magnets connecting inside the body are tragic.
Threat to electronics
Very strong magnetic fields can destroy records on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Implant safety
People with a pacemaker have to keep an large gap from magnets. The magnetic field can interfere with the operation of the life-saving device.
Mechanical processing
Dust generated during cutting of magnets is combustible. Do not drill into magnets unless you are an expert.
Do not underestimate power
Exercise caution. Neodymium magnets act from a long distance and snap with massive power, often quicker than you can move away.
Crushing risk
Protect your hands. Two large magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Permanent damage
Watch the temperature. Heating the magnet to high heat will destroy its magnetic structure and strength.
Compass and GPS
Remember: rare earth magnets generate a field that disrupts precision electronics. Keep a separation from your mobile, device, and GPS.
Avoid contact if allergic
Nickel alert: The nickel-copper-nickel coating contains nickel. If redness occurs, immediately stop handling magnets and use protective gear.
Magnet fragility
Protect your eyes. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
