Pros as well as cons of Nd2Fe14B magnets.
Pros
- They have constant strength, and over nearly ten years their performance decreases symbolically – ~1% (in testing),
- Magnets very well resist against demagnetization caused by external fields,
- By applying a decorative layer of nickel, the element gains an elegant look,
- The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of accurate machining as well as modifying to defined requirements,
- Significant place in modern technologies – they are utilized in HDD drives, drive modules, medical equipment, also complex engineering applications.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Weaknesses
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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 very resistant to heat
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing threads and complicated shapes in magnets, we recommend using a housing - magnetic mount.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these devices are able to disrupt the diagnostic process medical when they are in the body.
- With large orders the cost of neodymium magnets can be a barrier,
Lifting parameters
Maximum holding power of the magnet – what contributes to it?
- using a sheet made of mild steel, serving as a ideal flux conductor
- with a thickness of at least 10 mm
- with a plane cleaned and smooth
- without the slightest clearance between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at conditions approx. 20°C
Lifting capacity in practice – influencing factors
- Gap between surfaces – every millimeter of separation (caused e.g. by veneer or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Angle of force application – maximum parameter is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Steel grade – the best choice is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Temperature – heating the magnet causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
Warnings
Fire risk
Dust created during machining of magnets is combustible. Do not drill into magnets unless you are an expert.
Electronic devices
Device Safety: Neodymium magnets can damage data carriers and sensitive devices (heart implants, medical aids, timepieces).
ICD Warning
Warning for patients: Strong magnetic fields disrupt electronics. Maintain at least 30 cm distance or ask another person to handle the magnets.
GPS and phone interference
A powerful magnetic field negatively affects the functioning of magnetometers in smartphones and GPS navigation. Do not bring magnets near a smartphone to avoid breaking the sensors.
Sensitization to coating
Nickel alert: The nickel-copper-nickel coating consists of nickel. If skin irritation occurs, immediately stop handling magnets and use protective gear.
Serious injuries
Risk of injury: The pulling power is so immense that it can cause hematomas, crushing, and broken bones. Use thick gloves.
Caution required
Use magnets with awareness. Their huge power can shock even experienced users. Plan your moves and respect their power.
Permanent damage
Standard neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. This process is irreversible.
This is not a toy
These products are not intended for children. Eating several magnets can lead to them pinching intestinal walls, which constitutes a severe health hazard and necessitates urgent medical intervention.
Risk of cracking
Despite metallic appearance, the material is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
