Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their tremendous magnetic power, neodymium magnets offer the following advantages:
- Their magnetic field is maintained, and after approximately 10 years, it drops only by ~1% (according to research),
- They are highly resistant to demagnetization caused by external field interference,
- By applying a reflective layer of silver, the element gains a modern look,
- They have extremely strong magnetic induction on the surface of the magnet,
- They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
- The ability for accurate shaping and adaptation to custom needs – neodymium magnets can be manufactured in multiple variants of geometries, which enhances their versatility in applications,
- Wide application in advanced technical fields – they are used in data storage devices, electric drives, healthcare devices and sophisticated instruments,
- Compactness – despite their small size, they generate strong force, making them ideal for precision applications
Disadvantages of magnetic elements:
- They are prone to breaking when subjected to a strong impact. If the magnets are exposed to mechanical hits, they should be placed in a protective case. The steel housing, in the form of a holder, protects the magnet from breakage and additionally strengthens its overall robustness,
- Magnets lose field strength when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible field weakening (influenced by the magnet’s structure). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
- They rust in a damp environment. If exposed to rain, we recommend using waterproof magnets, such as those made of plastic,
- Using a cover – such as a magnetic holder – is advised due to the limitations in manufacturing fine shapes directly in the magnet,
- Potential hazard from tiny pieces may arise, if ingested accidentally, which is important in the health of young users. Additionally, miniature parts from these assemblies might interfere with diagnostics after being swallowed,
- In cases of large-volume purchasing, neodymium magnet cost may not be economically viable,
Maximum lifting force for a neodymium magnet – what affects it?
The given holding capacity of the magnet represents the highest holding force, calculated under optimal conditions, specifically:
- with the use of low-carbon steel plate serving as a magnetic yoke
- having a thickness of no less than 10 millimeters
- with a refined outer layer
- with zero air gap
- under perpendicular detachment force
- at room temperature
Lifting capacity in real conditions – factors
Practical lifting force is determined by factors, by priority:
- Air gap between the magnet and the plate, as even a very small distance (e.g. 0.5 mm) causes a drop in lifting force of up to 50%.
- Direction of applied force, because the maximum lifting capacity is achieved under perpendicular application. The force required to slide the magnet along the plate is usually several times lower.
- Thickness of the plate, as a plate that is too thin causes part of the magnetic flux not to be used and to remain wasted in the air.
- Material of the plate, because higher carbon content lowers holding force, while higher iron content increases it. The best choice is steel with high magnetic permeability and high saturation induction.
- Surface of the plate, because the more smooth and polished it is, the better the contact and consequently the greater the magnetic saturation.
- Operating temperature, since all permanent magnets have a negative temperature coefficient. This means that at high temperatures they are weaker, while at sub-zero temperatures they become slightly stronger.
* Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the holding force is lower. Moreover, even a minimal clearance {between} the magnet and the plate lowers the load capacity.
Exercise Caution with Neodymium Magnets
Do not place neodymium magnets near a computer HDD, TV, and wallet.
The strong magnetic field generated by neodymium magnets can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also damage devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Dust and powder from neodymium magnets are 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 demagnetize at high temperatures.
In certain circumstances, Neodymium magnets may experience demagnetization when subjected to high temperatures.
Do not give neodymium magnets to children.
Not all neodymium magnets are toys, so do not let children play with them. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
Keep neodymium magnets away from people with pacemakers.
In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes with the operation of a heart pacemaker. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their power can surprise you.
Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional disruption to the magnets.
Neodymium magnetic are delicate as well as can easily break as well as shatter.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.
The magnet is coated with nickel. Therefore, exercise caution if you have an allergy.
Studies show a small percentage of people have allergies to certain metals, including 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.
Avoid bringing neodymium magnets close to a phone or GPS.
Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
Neodymium magnets bounce and also clash mutually within a distance of several to around 10 cm from each other.
Exercise caution!
