Shopping tips

Advantages and disadvantages of neodymium magnets NdFeB.
Apart from their superior power, neodymium magnets have these key benefits:
- They virtually do not lose power, because even after 10 years, the decline in efficiency is only ~1% (in laboratory conditions),
- Their ability to resist magnetic interference from external fields is impressive,
- By applying a shiny layer of gold, the element gains a sleek look,
- They have exceptional magnetic induction on the surface of the magnet,
- These magnets tolerate high temperatures, often exceeding 230°C, when properly designed (in relation to profile),
- Thanks to the freedom in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in various configurations, which increases their functional possibilities,
- Key role in modern technologies – they are used in data storage devices, rotating machines, diagnostic apparatus along with sophisticated instruments,
- Thanks to their concentrated strength, small magnets offer high magnetic performance, with minimal size,
Disadvantages of NdFeB magnets:
- They are prone to breaking when subjected to a heavy impact. If the magnets are exposed to external force, we recommend in a protective case. The steel housing, in the form of a holder, protects the magnet from fracture , and at the same time reinforces its overall robustness,
- They lose magnetic force at high temperatures. Most neodymium magnets experience permanent degradation in strength when heated above 80°C (depending on the form and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
- Magnets exposed to wet conditions can corrode. Therefore, for outdoor applications, we suggest waterproof types made of coated materials,
- The use of a protective casing or external holder is recommended, since machining threads in neodymium magnets is restricted,
- Safety concern related to magnet particles may arise, if ingested accidentally, which is significant in the context of child safety. Furthermore, minuscule fragments from these products might hinder health screening when ingested,
- Due to the price of neodymium, their cost is above average,
Maximum lifting force for a neodymium magnet – what affects it?
The given strength of the magnet means the optimal strength, assessed in ideal conditions, namely:
- using a steel plate with low carbon content, serving as a magnetic circuit closure
- having a thickness of no less than 10 millimeters
- with a polished side
- with no separation
- with vertical force applied
- in normal thermal conditions
Lifting capacity in practice – influencing factors
Practical lifting force is determined by elements, by priority:
- Air gap between the magnet and the plate, since 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.
* Lifting capacity was determined by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance {between} the magnet and the plate lowers the holding force.
Safety Precautions
Dust and powder from neodymium magnets are highly flammable.
Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Neodymium magnets are among the strongest magnets on Earth. The astonishing force they generate between each other can shock you.
Familiarize yourself with our information to properly handle these magnets and avoid significant injuries to your body and prevent damage to the magnets.
Do not bring neodymium magnets close to GPS and smartphones.
Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.
Keep neodymium magnets away from TV, wallet, and computer HDD.
Strong magnetic fields emitted by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.
Do not give neodymium magnets to youngest children.
Neodymium magnets are not toys. Be cautious and make sure no child plays 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.
The magnet coating contains nickel, so be cautious if you have a nickel 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.
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. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.
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 magnetic are fragile and can easily crack and 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. At the moment of collision between the magnets, small sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.
Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.
Magnets will attract each other within a distance of several to about 10 cm from each other. Remember not to insert fingers between magnets or 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 a fracture.
