Pros and cons of Nd2Fe14B magnets.
Benefits
- They have stable power, and over nearly 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They maintain their magnetic properties even under strong external field,
- A magnet with a smooth nickel surface is more attractive,
- Magnets exhibit extremely high magnetic induction on the working surface,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to the potential of flexible molding and customization to specialized needs, neodymium magnets can be created in a broad palette of geometric configurations, which expands the range of possible applications,
- Fundamental importance in modern industrial fields – they find application in hard drives, electric drive systems, diagnostic systems, also technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Due to limitations in realizing threads and complex forms in magnets, we recommend using a housing - magnetic holder.
- Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Highest magnetic holding force – what affects it?
- with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- whose transverse dimension equals approx. 10 mm
- with an polished contact surface
- under conditions of no distance (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Practical aspects of lifting capacity – factors
- Distance – the presence of any layer (paint, tape, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Load vector – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the plate is usually many times lower (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Chemical composition of the base – low-carbon steel gives the best results. Higher carbon content decrease magnetic permeability and lifting capacity.
- Smoothness – full contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, however under parallel forces the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Safety rules for work with NdFeB magnets
Precision electronics
An intense magnetic field interferes with the operation of compasses in phones and navigation systems. Maintain magnets close to a smartphone to prevent breaking the sensors.
Combustion hazard
Machining of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Product not for children
Always keep magnets out of reach of children. Choking hazard is significant, and the effects of magnets connecting inside the body are fatal.
Medical implants
Individuals with a ICD should maintain an absolute distance from magnets. The magnetism can stop the operation of the implant.
Protect data
Powerful magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Stay away of at least 10 cm.
Heat warning
Standard neodymium magnets (N-type) lose power when the temperature exceeds 80°C. This process is irreversible.
Physical harm
Big blocks can crush fingers instantly. Under no circumstances put your hand between two attracting surfaces.
Warning for allergy sufferers
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, cease handling magnets and use protective gear.
Handling rules
Use magnets consciously. Their powerful strength can shock even professionals. Stay alert and respect their force.
Risk of cracking
NdFeB magnets are ceramic materials, which means they are fragile like glass. Impact of two magnets will cause them breaking into small pieces.
