Advantages and disadvantages of neodymium magnets.
Pros
- They do not lose magnetism, even over approximately ten years – the reduction in lifting capacity is only ~1% (theoretically),
- Neodymium magnets are characterized by extremely resistant to magnetic field loss caused by external magnetic fields,
- A magnet with a smooth nickel surface looks better,
- Magnets are characterized by very high magnetic induction on the outer layer,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Thanks to modularity in shaping and the capacity to adapt to specific needs,
- Fundamental importance in advanced technology sectors – they find application in mass storage devices, electric motors, advanced medical instruments, and industrial machines.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Disadvantages
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing nuts and complex shapes in magnets, we recommend using cover - magnetic mechanism.
- Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, tiny parts of these devices are able to complicate diagnosis medical after entering the body.
- With large orders the cost of neodymium magnets can be a barrier,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what it depends on?
- using a sheet made of low-carbon steel, acting as a ideal flux conductor
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with a surface cleaned and smooth
- without any clearance between the magnet and steel
- under perpendicular application of breakaway force (90-degree angle)
- at conditions approx. 20°C
Determinants of practical lifting force of a magnet
- Distance – existence of foreign body (paint, dirt, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Load vector – maximum parameter is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Cast iron may have worse magnetic properties.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal environment – heating the magnet results in weakening of induction. Check the thermal limit for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the holding force is lower. In addition, even a slight gap between the magnet and the plate decreases the lifting capacity.
Precautions when working with NdFeB magnets
Metal Allergy
It is widely known that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, prevent direct skin contact and opt for versions in plastic housing.
Electronic devices
Device Safety: Neodymium magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).
GPS and phone interference
A strong magnetic field negatively affects the functioning of compasses in smartphones and navigation systems. Do not bring magnets near a device to avoid breaking the sensors.
Permanent damage
Keep cool. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Bone fractures
Big blocks can crush fingers instantly. Under no circumstances put your hand betwixt two strong magnets.
Beware of splinters
Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Collision of two magnets will cause them breaking into shards.
Danger to the youngest
Always keep magnets out of reach of children. Risk of swallowing is high, and the effects of magnets connecting inside the body are fatal.
ICD Warning
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Handling rules
Use magnets with awareness. Their immense force can shock even experienced users. Be vigilant and do not underestimate their power.
Combustion hazard
Powder generated during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
