Advantages and disadvantages of Nd2Fe14B magnets.
Pros
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
- Neodymium magnets remain extremely resistant to loss of magnetic properties caused by external magnetic fields,
- A magnet with a smooth nickel surface is more attractive,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of exact forming and modifying to precise conditions,
- Wide application in advanced technology sectors – they find application in HDD drives, electric drive systems, advanced medical instruments, and technologically advanced constructions.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Limitations
- At strong impacts they can crack, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's 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 extremely resistant to heat
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in creating threads and complicated shapes in magnets, we recommend using casing - magnetic holder.
- Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Additionally, small elements of these devices can be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Maximum holding power of the magnet – what it depends on?
- with the application of a sheet made of low-carbon steel, ensuring maximum field concentration
- possessing a thickness of minimum 10 mm to avoid saturation
- with an ideally smooth contact surface
- with direct contact (no impurities)
- during detachment in a direction perpendicular to the plane
- at temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Steel grade – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
- Plate texture – ground elements guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was determined by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate lowers the holding force.
H&S for magnets
Risk of cracking
Neodymium magnets are ceramic materials, which means they are prone to chipping. Collision of two magnets leads to them breaking into small pieces.
Nickel allergy
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If redness occurs, cease working with magnets and use protective gear.
Warning for heart patients
People with a heart stimulator must keep an safe separation from magnets. The magnetic field can disrupt the operation of the implant.
Power loss in heat
Do not overheat. NdFeB magnets are susceptible to heat. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Do not give to children
NdFeB magnets are not suitable for play. Eating multiple magnets may result in them pinching intestinal walls, which poses a severe health hazard and requires immediate surgery.
Bodily injuries
Risk of injury: The attraction force is so immense that it can result in hematomas, crushing, and broken bones. Protective gloves are recommended.
Do not drill into magnets
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Keep away from computers
Data protection: Strong magnets can damage data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
Conscious usage
Use magnets consciously. Their huge power can shock even professionals. Plan your moves and do not underestimate their force.
Threat to navigation
An intense magnetic field interferes with the functioning of magnetometers in phones and GPS navigation. Keep magnets close to a device to prevent breaking the sensors.
