Magnetic properties of material N52
Physical properties of sintered neodymium magnets Nd2Fe14B at 20°C
Shopping tips
Advantages and disadvantages of NdFeB magnets.
In addition to their magnetic capacity, neodymium magnets provide the following advantages:
- They do not lose strength, even over around ten years – the drop in power is only ~1% (according to tests),
- Neodymium magnets are distinguished by highly resistant to loss of magnetic properties caused by external field sources,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnetic induction on the surface of the magnet turns out to be extremely intense,
- Neodymium magnets are known for exceptionally strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the magnetic form),
- Considering the ability of flexible shaping and adaptation to individualized needs, magnetic components can be manufactured in a wide range of shapes and sizes, which makes them more universal,
- Versatile presence in innovative solutions – they are used in hard drives, drive modules, diagnostic systems, also other advanced devices.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Disadvantages of NdFeB magnets:
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We recommend cover - magnetic holder, due to difficulties in creating nuts inside the magnet and complex forms.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that small elements of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Best holding force of the magnet in ideal parameters – what it depends on?
The lifting capacity listed is a theoretical maximum value executed under standard conditions:
- with the application of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- with a cross-section of at least 10 mm
- characterized by lack of roughness
- under conditions of ideal adhesion (surface-to-surface)
- during pulling in a direction vertical to the plane
- at temperature approx. 20 degrees Celsius
Practical lifting capacity: influencing factors
In practice, the real power results from many variables, listed from crucial:
- Gap (betwixt the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, rust or debris).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Material type – the best choice is pure iron steel. Hardened steels may attract less.
- Smoothness – full contact is possible only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Heat – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).
* Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the holding force is lower. Additionally, even a small distance {between} the magnet’s surface and the plate reduces the lifting capacity.
Exercise Caution with Neodymium Magnets
Neodymium magnetic are particularly delicate, resulting in their breakage.
Neodymium magnets are highly delicate, and by joining them in an uncontrolled manner, they will crack. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.
Dust and powder from neodymium magnets are highly flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Neodymium magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant injuries.
Magnets will jump and contact together within a distance of several to almost 10 cm from each other.
Do not give neodymium magnets to children.
Neodymium magnets are not toys. You cannot allow them to become toys for children. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
Neodymium magnets are the most powerful magnets ever created, and their strength can shock you.
Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.
Neodymium magnets can become demagnetized at high temperatures.
Even though magnets have been observed to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.
The magnet is coated with nickel - be careful if you have an allergy.
Studies clearly indicate a small percentage of people who suffer from metal allergies such as nickel. An allergic reaction often manifests as skin redness and rash. If you have a nickel allergy, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
Do not bring neodymium magnets close to GPS and smartphones.
Neodymium magnets are a source of strong magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets should not be near people with pacemakers.
Neodymium magnets produce strong magnetic fields that can interfere with the operation of a heart pacemaker. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.
Keep neodymium magnets away from TV, wallet, and computer HDD.
Magnetic fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
