Magnetic properties of material N52
Physical properties of sintered neodymium magnets Nd2Fe14B at 20°C
Shopping tips
Pros and cons of neodymium magnets.
Apart from their superior magnetic energy, neodymium magnets have these key benefits:
- They retain full power for nearly 10 years – the drop is just ~1% (according to analyses),
- They are extremely resistant to demagnetization induced by presence of other magnetic fields,
- A magnet with a metallic gold surface is more attractive,
- Magnets have huge magnetic induction on the outer side,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures reaching 230°C and above...
- Thanks to modularity in designing and the ability to modify to unusual requirements,
- Key role in modern industrial fields – they are used in magnetic memories, electromotive mechanisms, precision medical tools, as well as other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages of NdFeB magnets:
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a strong case, which not only secures 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 stable to moisture, when using outdoors
- We suggest a housing - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated forms.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. Furthermore, small elements of these devices are able to 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 can limit application in large quantities
Maximum lifting force for a neodymium magnet – what it depends on?
The force parameter is a result of laboratory testing conducted under the following configuration:
- on a block made of mild steel, optimally conducting the magnetic flux
- with a cross-section minimum 10 mm
- characterized by lack of roughness
- under conditions of no distance (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- in neutral thermal conditions
Impact of factors on magnetic holding capacity in practice
Holding efficiency is influenced by working environment parameters, mainly (from priority):
- Space between magnet and steel – every millimeter of separation (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Direction of force – highest force is reached only during perpendicular pulling. The shear force of the magnet along the surface is usually many times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Chemical composition of the base – low-carbon steel attracts best. Alloy steels lower magnetic properties and lifting capacity.
- Smoothness – full contact is possible only on polished steel. Rough texture create air cushions, weakening the magnet.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
* Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the lifting capacity is smaller. Additionally, even a slight gap {between} the magnet and the plate lowers the holding force.
Safety rules for work with NdFeB magnets
Respect the power
Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Combustion hazard
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Electronic devices
Data protection: Neodymium magnets can damage data carriers and delicate electronics (heart implants, hearing aids, timepieces).
Metal Allergy
Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. For allergy sufferers, refrain from direct skin contact or select encased magnets.
No play value
These products are not toys. Accidental ingestion of a few magnets can lead to them attracting across intestines, which poses a direct threat to life and necessitates urgent medical intervention.
Operating temperature
Do not overheat. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, ask us about HT versions (H, SH, UH).
ICD Warning
Patients with a ICD must maintain an safe separation from magnets. The magnetic field can stop the functioning of the implant.
Impact on smartphones
Navigation devices and smartphones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can permanently damage the internal compass in your phone.
Crushing risk
Protect your hands. Two large magnets will join instantly with a force of massive weight, crushing everything in their path. Be careful!
Material brittleness
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
