Shopping tips
Moreover, although neodymium is part of the strongest magnets, they are prone to corrosion in humid environments. Therefore, they are coated with a coating of gold-nickel to increase their durability. Interestingly that NdFeB neodymium magnets are about 13% lighter than SmCo magnets and, despite their power, easily break, which requires care during their handling. For this reason, any mechanical processing should be done before they are magnetized.
In terms of safety, there are many recommendations regarding the use of these magnets. It is advisable to avoid their use in acidic, basic, organic environments or in solvents, 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 conditions of high humidity. Therefore, they are often covered with thin coatings, such as silver, to protect them from external factors and prolong their durability. Temperatures exceeding 130°C can cause a deterioration of their magnetic properties, 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 environments, 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 lose their magnetic strength.
Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to their pulling strength, neodymium magnets provide the following advantages:
- Their strength is maintained, and after around 10 years, it drops only by ~1% (according to research),
- They show exceptional resistance to demagnetization from outside magnetic sources,
- Because of the reflective layer of gold, the component looks high-end,
- The outer field strength of the magnet shows remarkable magnetic properties,
- Thanks to their high temperature resistance, they can operate (depending on the geometry) even at temperatures up to 230°C or more,
- The ability for custom shaping or adjustment to custom needs – neodymium magnets can be manufactured in many forms and dimensions, which enhances their versatility in applications,
- Important function in new technology industries – they find application in hard drives, electric drives, diagnostic apparatus as well as technologically developed systems,
- Thanks to their concentrated strength, small magnets offer high magnetic performance, with minimal size,
Disadvantages of NdFeB magnets:
- They can break when subjected to a sudden impact. If the magnets are exposed to mechanical hits, it is suggested to place them in a metal holder. The steel housing, in the form of a holder, protects the magnet from fracture while also increases its overall resistance,
- They lose field intensity at increased temperatures. Most neodymium magnets experience permanent reduction in strength when heated above 80°C (depending on the shape and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
- They rust in a moist environment. For outdoor use, we recommend using waterproof magnets, such as those made of non-metallic materials,
- Using a cover – such as a magnetic holder – is advised due to the restrictions in manufacturing complex structures directly in the magnet,
- Potential hazard due to small fragments may arise, when consumed by mistake, which is significant in the family environments. Furthermore, small elements from these assemblies might interfere with diagnostics once in the system,
- In cases of tight budgets, neodymium magnet cost may not be economically viable,
Precautions
Neodymium magnetic are delicate as well as can easily crack as well as get damaged.
Neodymium magnets are fragile as well as will shatter 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. At the moment of collision between the magnets, tiny sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.
Dust and powder from neodymium magnets are 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.
It is important to maintain neodymium magnets away from youngest children.
Neodymium magnets are not toys. You cannot allow them to become toys for children. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
Under no circumstances should neodymium magnets be brought 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.
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 swellings.
Magnets attract each other within a distance of several to around 10 cm from each other. Remember not to insert 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 even a fracture.
Neodymium magnets can demagnetize at high temperatures.
Even though magnets have been found to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.
You should keep neodymium magnets at a safe distance from the wallet, computer, and TV.
Strong 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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
Neodymium magnets are over 10 times more powerful than ferrite magnets (the ones in speakers), and their power can shock you.
Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.
If you have a nickel allergy, avoid contact with neodymium magnets.
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.
Neodymium magnets are not recommended for people with pacemakers.
Neodymium magnets produce strong magnetic fields that can interfere 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.
