Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their remarkable pulling force, neodymium magnets offer the following advantages:
- Their magnetic field remains stable, and after around ten years, it drops only by ~1% (according to research),
- They show superior resistance to demagnetization from external magnetic fields,
- By applying a reflective layer of gold, the element gains a clean look,
- They exhibit extremely high levels of magnetic induction near the outer area of the magnet,
- These magnets tolerate high temperatures, often exceeding 230°C, when properly designed (in relation to profile),
- The ability for accurate shaping or adjustment to individual needs – neodymium magnets can be manufactured in many forms and dimensions, which enhances their versatility in applications,
- Wide application in advanced technical fields – they are used in HDDs, electric motors, diagnostic apparatus and other advanced devices,
- Compactness – despite their small size, they provide high effectiveness, making them ideal for precision applications
Disadvantages of rare earth magnets:
- They can break when subjected to a powerful impact. If the magnets are exposed to shocks, it is suggested to place them in a metal holder. The steel housing, in the form of a holder, protects the magnet from fracture , and at the same time enhances its overall strength,
- Magnets lose magnetic efficiency when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible performance loss (influenced by the magnet’s dimensions). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
- Magnets exposed to humidity can corrode. Therefore, for outdoor applications, it's best to use waterproof types made of rubber,
- Limited ability to create threads in the magnet – the use of a magnetic holder is recommended,
- Health risk linked to microscopic shards may arise, if ingested accidentally, which is significant in the health of young users. Moreover, small elements from these assemblies have the potential to complicate medical imaging once in the system,
- Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications
Maximum lifting capacity of the magnet – what contributes to it?
The given strength of the magnet corresponds to the optimal strength, assessed in the best circumstances, namely:
- with the use of low-carbon steel plate serving as a magnetic yoke
- having a thickness of no less than 10 millimeters
- with a polished side
- with no separation
- under perpendicular detachment force
- at room temperature
Practical lifting capacity: influencing factors
In practice, the holding capacity of a magnet is conditioned by these factors, in descending order of importance:
- Air gap between the magnet and the plate, because 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 checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance {between} the magnet and the plate reduces the load capacity.
Exercise Caution with Neodymium Magnets
Neodymium magnets can demagnetize at high temperatures.
Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.
Neodymium magnets are delicate and can easily break and shatter.
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. At the moment of collision between the magnets, small metal fragments can be dispersed in different directions.
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.
Neodymium magnets are the most powerful magnets ever invented. Their power can shock 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.
It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.
Magnets attract each other within a distance of several to around 10 cm from each other. Remember not to place fingers between magnets or alternatively in their path when they attract. Magnets, depending on their size, are able even cut off a finger or there can be a severe pressure or a fracture.
People with pacemakers are advised to avoid neodymium magnets.
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.
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 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.
Do not give neodymium magnets to children.
Neodymium magnets are not toys. Be cautious and make sure no child plays with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.
Keep neodymium magnets as far away as possible from GPS and smartphones.
Neodymium magnets are a source of intense magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
