Pros as well as cons of Nd2Fe14B magnets.
Strengths
- They do not lose magnetism, even after around 10 years – the reduction in power is only ~1% (according to tests),
- They do not lose their magnetic properties even under external field action,
- In other words, due to the glossy finish of nickel, the element becomes visually attractive,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to flexibility in constructing and the capacity to adapt to unusual requirements,
- Wide application in advanced technology sectors – they serve a role in mass storage devices, motor assemblies, medical equipment, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in compact constructions
Limitations
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- Due to limitations in creating threads and complex shapes in magnets, we recommend using cover - magnetic holder.
- Potential hazard related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these products are able to be problematic in diagnostics medical when they are in the body.
- 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
Pull force analysis
Detachment force of the magnet in optimal conditions – what it depends on?
- on a plate made of structural steel, perfectly concentrating the magnetic field
- possessing a massiveness of at least 10 mm to ensure full flux closure
- characterized by smoothness
- without any clearance between the magnet and steel
- during pulling in a direction vertical to the plane
- in stable room temperature
Practical aspects of lifting capacity – factors
- Gap between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Steel type – mild steel gives the best results. Alloy admixtures reduce magnetic permeability and lifting capacity.
- Surface condition – smooth surfaces ensure maximum contact, which increases force. Uneven metal reduce efficiency.
- Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet and the plate lowers the load capacity.
Safety rules for work with neodymium magnets
Warning for heart patients
Warning for patients: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or request help to work with the magnets.
Do not give to children
These products are not suitable for play. Eating multiple magnets can lead to them attracting across intestines, which poses a critical condition and requires immediate surgery.
Pinching danger
Large magnets can crush fingers instantly. Do not put your hand between two attracting surfaces.
Demagnetization risk
Keep cool. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Protect data
Powerful magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Nickel allergy
Certain individuals have a contact allergy to Ni, which is the common plating for neodymium magnets. Extended handling can result in a rash. We suggest use safety gloves.
Magnet fragility
Watch out for shards. Magnets can fracture upon violent connection, ejecting shards into the air. Wear goggles.
Mechanical processing
Dust generated during cutting of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Immense force
Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Compass and GPS
Be aware: rare earth magnets generate a field that disrupts sensitive sensors. Keep a safe distance from your phone, tablet, and navigation systems.
