Pros and cons of Nd2Fe14B magnets.
Benefits
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- They have excellent resistance to magnetic field loss when exposed to external magnetic sources,
- In other words, due to the shiny finish of gold, the element is aesthetically pleasing,
- Magnets exhibit extremely high magnetic induction on the surface,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to the option of free molding and adaptation to specialized projects, NdFeB magnets can be modeled in a wide range of shapes and sizes, which makes them more universal,
- Key role in innovative solutions – they are commonly used in mass storage devices, electromotive mechanisms, precision medical tools, as well as other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Cons
- To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets lose power 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 extremely resistant to heat
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of producing nuts in the magnet and complex shapes - recommended is casing - magnet mounting.
- Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these devices are able to disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum lifting force for a neodymium magnet – what affects it?
- on a block made of structural steel, effectively closing the magnetic flux
- possessing a thickness of minimum 10 mm to avoid saturation
- with an polished contact surface
- under conditions of no distance (surface-to-surface)
- for force acting at a right angle (pull-off, not shear)
- in neutral thermal conditions
Practical aspects of lifting capacity – factors
- Air gap (between the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
- Force direction – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Base massiveness – insufficiently thick steel does not accept the full field, causing part of the power to be lost to the other side.
- Material composition – different alloys attracts identically. High carbon content weaken the attraction effect.
- Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the holding force is lower. Additionally, even a small distance between the magnet and the plate decreases the load capacity.
H&S for magnets
Implant safety
Warning for patients: Powerful magnets affect electronics. Keep minimum 30 cm distance or request help to work with the magnets.
Swallowing risk
Adult use only. Small elements can be swallowed, leading to intestinal necrosis. Keep out of reach of kids and pets.
Handling rules
Handle magnets with awareness. Their immense force can surprise even experienced users. Stay alert and respect their force.
Dust is flammable
Fire warning: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.
Heat warning
Avoid heat. Neodymium magnets are susceptible to temperature. If you need operation above 80°C, look for HT versions (H, SH, UH).
Threat to electronics
Data protection: Strong magnets can damage payment cards and delicate electronics (pacemakers, hearing aids, timepieces).
Threat to navigation
Remember: neodymium magnets generate a field that confuses sensitive sensors. Maintain a separation from your phone, device, and GPS.
Pinching danger
Large magnets can break fingers instantly. Under no circumstances place your hand between two strong magnets.
Skin irritation risks
Nickel alert: The nickel-copper-nickel coating contains nickel. If redness occurs, cease working with magnets and wear gloves.
Fragile material
NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Collision of two magnets leads to them shattering into shards.
