Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- They retain attractive force for around 10 years – the loss is just ~1% (in theory),
- Neodymium magnets remain extremely resistant to magnetic field loss caused by external interference,
- By covering with a shiny coating of gold, the element has an elegant look,
- The surface of neodymium magnets generates a unique magnetic field – this is a key feature,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- In view of the potential of flexible molding and customization to custom needs, NdFeB magnets can be modeled in a wide range of shapes and sizes, which expands the range of possible applications,
- Key role in high-tech industry – they find application in computer drives, electric motors, medical devices, as well as other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Limited ability of making nuts in the magnet and complex shapes - recommended is casing - magnet mounting.
- Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Furthermore, small components of these magnets can disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Maximum lifting force for a neodymium magnet – what contributes to it?
- using a sheet made of high-permeability steel, functioning as a ideal flux conductor
- possessing a massiveness of min. 10 mm to avoid saturation
- with a surface free of scratches
- with total lack of distance (without paint)
- during pulling in a direction perpendicular to the mounting surface
- in stable room temperature
Practical aspects of lifting capacity – factors
- Air gap (betwixt the magnet and the metal), because even a tiny distance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to paint, rust or dirt).
- Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Plate thickness – too thin plate does not accept the full field, causing part of the power to be lost into the air.
- Metal type – not every steel attracts identically. High carbon content worsen the attraction effect.
- Surface condition – ground elements ensure maximum contact, which improves force. Rough surfaces weaken the grip.
- Thermal environment – heating the magnet results in weakening of force. Check the thermal limit for a given model.
Lifting capacity was measured with the use of a polished steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
Safety rules for work with NdFeB magnets
Electronic devices
Data protection: Strong magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, mechanical watches).
Serious injuries
Pinching hazard: The pulling power is so great that it can result in hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Beware of splinters
Neodymium magnets are ceramic materials, which means they are fragile like glass. Impact of two magnets leads to them breaking into shards.
Life threat
Warning for patients: Strong magnetic fields affect electronics. Maintain at least 30 cm distance or ask another person to handle the magnets.
Flammability
Machining of NdFeB material carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Magnetic interference
Remember: neodymium magnets generate a field that confuses precision electronics. Maintain a separation from your phone, device, and navigation systems.
Metal Allergy
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If redness occurs, immediately stop handling magnets and use protective gear.
Handling guide
Use magnets with awareness. Their huge power can surprise even experienced users. Be vigilant and respect their force.
No play value
Absolutely keep magnets out of reach of children. Choking hazard is high, and the consequences of magnets clamping inside the body are tragic.
Heat sensitivity
Standard neodymium magnets (N-type) lose power when the temperature surpasses 80°C. Damage is permanent.
