Magnetic properties of material N52
Physical properties of sintered neodymium magnets Nd2Fe14B at 20°C
Shopping tips
Pros as well as cons of NdFeB magnets.
Besides their magnetic performance, neodymium magnets are valued for these benefits:
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (based on calculations),
- Neodymium magnets remain extremely resistant to demagnetization caused by magnetic disturbances,
- In other words, due to the smooth layer of gold, the element gains visual value,
- They show high magnetic induction at the operating surface, which improves attraction properties,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to versatility in constructing and the capacity to adapt to client solutions,
- Versatile presence in high-tech industry – they serve a role in mass storage devices, motor assemblies, medical devices, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in small systems
Disadvantages of neodymium magnets:
- At strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- We suggest cover - magnetic mount, due to difficulties in producing nuts inside the magnet and complicated forms.
- Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these products are able to be problematic in diagnostics medical when they are in the body.
- Due to complex production process, their price is relatively high,
Maximum magnetic pulling force – what contributes to it?
Breakaway force was defined for the most favorable conditions, including:
- with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- possessing a thickness of minimum 10 mm to avoid saturation
- characterized by lack of roughness
- with total lack of distance (no paint)
- during detachment in a direction perpendicular to the plane
- at ambient temperature room level
Practical lifting capacity: influencing factors
Please note that the magnet holding may be lower subject to elements below, in order of importance:
- Distance – the presence of any layer (paint, dirt, air) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Steel type – mild steel gives the best results. Higher carbon content reduce magnetic permeability and holding force.
- Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Temperature influence – high temperature reduces magnetic field. Too high temperature can permanently damage the magnet.
* Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a slight gap {between} the magnet and the plate lowers the load capacity.
Precautions when working with neodymium magnets
Danger to the youngest
Absolutely keep magnets away from children. Choking hazard is significant, and the effects of magnets connecting inside the body are tragic.
Nickel coating and allergies
Some people experience a hypersensitivity to Ni, which is the typical protective layer for neodymium magnets. Frequent touching may cause dermatitis. It is best to wear protective gloves.
Thermal limits
Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Danger to pacemakers
Patients with a pacemaker have to maintain an large gap from magnets. The magnetic field can disrupt the functioning of the implant.
GPS and phone interference
Navigation devices and smartphones are extremely susceptible to magnetism. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.
Fire risk
Mechanical processing of NdFeB material carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Bodily injuries
Watch your fingers. Two large magnets will join instantly with a force of massive weight, destroying everything in their path. Be careful!
Immense force
Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Protect data
Data protection: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, hearing aids, timepieces).
Beware of splinters
Protect your eyes. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Wear goggles.
