Advantages as well as disadvantages of Nd2Fe14B magnets.
Advantages
- They do not lose strength, even over around ten years – the drop in lifting capacity is only ~1% (based on measurements),
- They do not lose their magnetic properties even under external field action,
- A magnet with a shiny gold surface has better aesthetics,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures reaching 230°C and above...
- In view of the possibility of accurate shaping and adaptation to unique requirements, magnetic components can be modeled in a wide range of shapes and sizes, which makes them more universal,
- Significant place in high-tech industry – they find application in HDD drives, brushless drives, medical equipment, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in small systems
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only protects them against impacts but also raises their durability
- Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 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 resistant to moisture, in case of application outdoors
- We suggest cover - magnetic mount, due to difficulties in producing nuts inside the magnet and complex forms.
- Possible danger related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. It is also worth noting that small elements of these products are able to complicate diagnosis medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum lifting force for a neodymium magnet – what it depends on?
- using a base made of low-carbon steel, acting as a ideal flux conductor
- whose transverse dimension reaches at least 10 mm
- with an ground touching surface
- under conditions of gap-free contact (surface-to-surface)
- during pulling in a direction vertical to the mounting surface
- at ambient temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Distance – the presence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Material type – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
- Surface finish – full contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under shearing force the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet and the plate lowers the load capacity.
Safe handling of neodymium magnets
Magnetic media
Powerful magnetic fields can destroy records on payment cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Danger to pacemakers
Individuals with a ICD must maintain an safe separation from magnets. The magnetic field can stop the functioning of the implant.
Warning for allergy sufferers
Certain individuals suffer from a sensitization to nickel, which is the typical protective layer for neodymium magnets. Prolonged contact can result in skin redness. We suggest wear safety gloves.
This is not a toy
These products are not toys. Eating a few magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and requires urgent medical intervention.
Machining danger
Drilling and cutting of neodymium magnets carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Powerful field
Before use, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Beware of splinters
Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Hand protection
Large magnets can break fingers in a fraction of a second. Never place your hand between two attracting surfaces.
Operating temperature
Keep cool. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, inquire about HT versions (H, SH, UH).
Compass and GPS
A strong magnetic field disrupts the functioning of magnetometers in smartphones and GPS navigation. Maintain magnets close to a smartphone to avoid damaging the sensors.
