Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to their tremendous strength, neodymium magnets offer the following advantages:
- They virtually do not lose strength, because even after ten years, the decline in efficiency is only ~1% (in laboratory conditions),
- They are highly resistant to demagnetization caused by external magnetic sources,
- Thanks to the shiny finish and nickel coating, they have an visually attractive appearance,
- They exhibit superior levels of magnetic induction near the outer area of the magnet,
- With the right combination of magnetic alloys, they reach significant thermal stability, enabling operation at or above 230°C (depending on the form),
- Thanks to the flexibility in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in various configurations, which expands their functional possibilities,
- Significant impact in modern technologies – they serve a purpose in computer drives, rotating machines, healthcare devices and technologically developed systems,
- Relatively small size with high magnetic force – neodymium magnets offer strong power in small dimensions, which makes them useful in small systems
Disadvantages of magnetic elements:
- They are prone to breaking when subjected to a sudden impact. If the magnets are exposed to external force, it is advisable to use in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from damage and additionally reinforces its overall durability,
- High temperatures may significantly reduce the strength of neodymium magnets. Typically, above 80°C, they experience permanent deterioration in performance (depending on height). To prevent this, we offer heat-resistant magnets marked [AH], capable of working up to 230°C, which makes them perfect for high-temperature use,
- Due to corrosion risk in humid conditions, it is advisable to use sealed magnets made of protective material for outdoor use,
- The use of a protective casing or external holder is recommended, since machining fine details in neodymium magnets is difficult,
- Possible threat due to small fragments may arise, in case of ingestion, which is important in the health of young users. Additionally, minuscule fragments from these devices have the potential to complicate medical imaging when ingested,
- Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications
Magnetic strength at its maximum – what affects it?
The given pulling force of the magnet means the maximum force, calculated in the best circumstances, that is:
- with mild steel, serving as a magnetic flux conductor
- of a thickness of at least 10 mm
- with a refined outer layer
- in conditions of no clearance
- under perpendicular detachment force
- at room temperature
Practical lifting capacity: influencing factors
In practice, the holding capacity of a magnet is conditioned by the following aspects, from crucial to less important:
- Air gap between the magnet and the plate, because 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 checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a small distance {between} the magnet and the plate lowers the lifting capacity.
Handle with Care: Neodymium Magnets
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.
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.
Neodymium magnets jump and also touch each other mutually within a distance of several to almost 10 cm from each other.
Neodymium magnets should not be near 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.
You should keep neodymium magnets at a safe distance from the wallet, computer, and TV.
Neodymium magnets generate intense magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Avoid contact with neodymium magnets if you have a nickel 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.
Neodymium magnets are the most powerful magnets ever invented. Their strength can shock you.
To handle magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.
Neodymium magnetic are characterized by their fragility, which can cause them to shatter.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. 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.
Keep neodymium magnets away from GPS and smartphones.
Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Do not give neodymium magnets to youngest children.
Remember that 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 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.
Caution!
