Advantages and disadvantages of neodymium magnets.
Strengths
- They have constant strength, and over around 10 years their performance decreases symbolically – ~1% (in testing),
- Magnets very well protect themselves against loss of magnetization caused by foreign field sources,
- In other words, due to the glossy layer of silver, the element looks attractive,
- Magnetic induction on the working part of the magnet is very high,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Due to the possibility of precise forming and customization to individualized requirements, magnetic components can be produced in a broad palette of shapes and sizes, which expands the range of possible applications,
- Universal use in future technologies – they are commonly used in computer drives, brushless drives, precision medical tools, and industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can reduce their power 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 corrode. Therefore during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of producing nuts in the magnet and complicated forms - recommended is cover - magnet mounting.
- Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, small elements of these magnets are able to be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what affects it?
- with the application of a sheet made of special test steel, ensuring full magnetic saturation
- whose thickness is min. 10 mm
- with an polished contact surface
- without the slightest insulating layer between the magnet and steel
- under axial force direction (90-degree angle)
- at ambient temperature room level
Practical aspects of lifting capacity – factors
- Clearance – the presence of any layer (rust, tape, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Metal type – not every steel reacts the same. Alloy additives worsen the attraction effect.
- Surface quality – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Temperature influence – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under parallel forces the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate decreases the lifting capacity.
Safe handling of NdFeB magnets
Risk of cracking
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Operating temperature
Do not overheat. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Warning for allergy sufferers
It is widely known that nickel (the usual finish) is a strong allergen. If you have an allergy, prevent touching magnets with bare hands and select encased magnets.
Electronic hazard
Very strong magnetic fields can corrupt files on payment cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.
Handling rules
Before use, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Pacemakers
Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Keep away from electronics
Note: rare earth magnets generate a field that interferes with sensitive sensors. Maintain a separation from your phone, tablet, and navigation systems.
No play value
Neodymium magnets are not toys. Eating multiple magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and necessitates immediate surgery.
Pinching danger
Big blocks can smash fingers instantly. Under no circumstances put your hand betwixt two attracting surfaces.
Fire warning
Dust generated during cutting of magnets is combustible. Avoid drilling into magnets unless you are an expert.
