Shopping tips
Moreover, even though neodymium is a component of the strongest magnets, they are prone to corrosion in humid environments. Therefore, they are coated with a coating of gold to protect them from corrosion. It's worth noting that NdFeB neodymium magnets are about 13% lighter than SmCo magnets and, despite their power, are brittle, which requires special caution during their handling. Therefore, any mechanical processing should be done before they are magnetized.
In terms of safety, there are several recommendations regarding the use of these magnets. It is advisable to avoid their use in acidic, basic, organic environments or where solvents are present, and also in water or oil. Additionally, they can damage data on magnetic cards and hard drives, although data deletion using a neodymium magnet is not always certain.
In terms of properties in different environments, neodymium magnets are susceptible to corrosion, especially in humid conditions. Therefore, they are often covered with thin coatings, such as silver, to shield them from external factors and prolong their durability. Temperatures exceeding 130°C can cause a deterioration of their magnetic strength, although there are particular types of neodymium magnets that can withstand temperatures up to 230°C.
As for risks, it is important to avoid using neodymium magnets in acidic environments, basic conditions, organic or solvent environments, unless they are properly protected. Additionally, their use is not recommended in wet conditions, oil, or in an atmosphere containing hydrogen, as they may forfeit their magnetic strength.
Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their magnetic capacity, neodymium magnets provide the following advantages:
- They retain their attractive force for almost ten years – the loss is just ~1% (according to analyses),
- They show exceptional resistance to demagnetization from outside magnetic sources,
- Because of the brilliant layer of gold, the component looks high-end,
- The outer field strength of the magnet shows remarkable magnetic properties,
- Neodymium magnets are known for strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the geometry),
- The ability for precise shaping or adjustment to custom needs – neodymium magnets can be manufactured in multiple variants of geometries, which amplifies their functionality across industries,
- Wide application in cutting-edge sectors – they are used in data storage devices, electric drives, healthcare devices along with technologically developed systems,
- Thanks to their power density, small magnets offer high magnetic performance, in miniature format,
Disadvantages of neodymium magnets:
- They are prone to breaking when subjected to a heavy impact. If the magnets are exposed to physical collisions, they should be placed in a metal holder. The steel housing, in the form of a holder, protects the magnet from fracture and additionally increases its overall durability,
- They lose magnetic force at extreme temperatures. Most neodymium magnets experience permanent degradation 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,
- Due to corrosion risk in humid conditions, it is wise to use sealed magnets made of synthetic coating for outdoor use,
- Using a cover – such as a magnetic holder – is advised due to the challenges in manufacturing complex structures directly in the magnet,
- Possible threat linked to microscopic shards may arise, in case of ingestion, which is crucial in the protection of children. Moreover, tiny components from these products may disrupt scanning when ingested,
- Due to expensive raw materials, their cost is relatively high,
Precautions
You should keep neodymium magnets at a safe distance from the wallet, computer, and TV.
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. Do not forget to keep neodymium magnets away from these electronic devices.
Keep neodymium magnets as far away as possible from GPS and smartphones.
Neodymium magnets are a source of strong magnetic fields that cause interference 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.
Neodymium magnetic are extremely fragile, leading to their cracking.
Neodymium magnetic are fragile as well as will crack if allowed to collide with each other, even from a distance of a few centimeters. 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 - be careful 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.
Do not give neodymium magnets to youngest children.
Neodymium magnets are not toys. You cannot allow them to become toys for children. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
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 correctly handle these magnets and avoid significant injuries to your body and prevent damage to the magnets.
Dust and powder from neodymium magnets are 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 can attract to each other, pinch the skin, and cause significant swellings.
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 in their path when attract. Magnets, depending on their size, can even cut off a finger or alternatively 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. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.
