Advantages and disadvantages of neodymium magnets NdFeB.
Besides their high retention, neodymium magnets are valued for these benefits:
- They retain their attractive force for nearly 10 years – the drop is just ~1% (according to analyses),
- They protect against demagnetization induced by surrounding magnetic fields remarkably well,
- Because of the brilliant layer of silver, the component looks aesthetically refined,
- They exhibit superior levels of magnetic induction near the outer area of the magnet,
- With the right combination of materials, they reach excellent thermal stability, enabling operation at or above 230°C (depending on the design),
- The ability for custom shaping or adjustment to individual needs – neodymium magnets can be manufactured in multiple variants of geometries, which enhances their versatility in applications,
- Wide application in new technology industries – they find application in data storage devices, rotating machines, healthcare devices and high-tech tools,
- Thanks to their power density, small magnets offer high magnetic performance, in miniature format,
Disadvantages of magnetic elements:
- They may fracture when subjected to a powerful impact. If the magnets are exposed to shocks, it is advisable to use in a metal holder. The steel housing, in the form of a holder, protects the magnet from fracture and additionally enhances its overall resistance,
- They lose field intensity at extreme temperatures. Most neodymium magnets experience permanent reduction in strength when heated above 80°C (depending on the dimensions and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
- They rust in a damp environment – during outdoor use, we recommend using encapsulated magnets, such as those made of plastic,
- Limited ability to create internal holes in the magnet – the use of a magnetic holder is recommended,
- Possible threat from tiny pieces may arise, in case of ingestion, which is crucial in the protection of children. Additionally, tiny components from these products can hinder health screening after being swallowed,
- Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications
Optimal lifting capacity of a neodymium magnet – what contributes to it?
The given holding capacity of the magnet represents the highest holding force, calculated under optimal conditions, namely:
- with mild steel, used as a magnetic flux conductor
- with a thickness of minimum 10 mm
- with a polished side
- with zero air gap
- under perpendicular detachment force
- at room temperature
Impact of factors on magnetic holding capacity in practice
In practice, the holding capacity of a magnet is affected by the following aspects, in descending order of importance:
- Air gap between the magnet and the plate, as even a very small distance (e.g. 0.5 mm) can cause 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 measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the load capacity is reduced by as much as 75%. Moreover, even a slight gap {between} the magnet and the plate lowers the lifting capacity.
Handle Neodymium Magnets with Caution
Magnets made of neodymium are incredibly delicate, they easily fall apart and can become damaged.
Neodymium magnetic are extremely 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. At the moment of connection between the magnets, sharp metal fragments can be dispersed in different directions.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their strength can surprise you.
Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional disruption to the magnets.
Make sure not to bring neodymium magnets close to the 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. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
The magnet coating is made of nickel, so be cautious 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.
Magnets will attract each other within a distance of several to about 10 cm from each other. Remember not to put fingers between magnets or alternatively in their path when attract. Magnets, depending on their size, are able even cut off a finger or there can be a significant pressure or even a fracture.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Neodymium magnets generate intense magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets can become demagnetized at high temperatures.
Although magnets are generally resilient, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
People with pacemakers are advised to avoid neodymium magnets.
Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.
It is important to maintain neodymium magnets away from youngest children.
Neodymium magnets are not toys. Do not allow children to play with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
