Shopping tips
Moreover, even though neodymium is a component of the strongest magnets, they are susceptible to corrosion in humid environments. For this reason, they are coated with a coating of epoxy to increase their durability. Interestingly that NdFeB neodymium magnets are about 13% lighter than SmCo magnets and, despite their power, are brittle, 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 several 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. Furthermore, they can damage data on magnetic cards and hard drives, although data deletion using a neodymium magnet is not guaranteed.
In terms of properties in different environments, neodymium magnets are sensitive to corrosion, especially in humid conditions. Therefore, they are often covered with coatings, such as nickel, to protect them from environmental factors and extend their lifespan. Temperatures exceeding 130°C can result in a deterioration of their magnetic properties, although there are specific types of neodymium magnets that can withstand temperatures up to 230°C.
As for potential dangers, it is important to avoid using neodymium magnets in acidic environments, basic conditions, organic or solvent environments, unless they are insulated. Additionally, their use is not recommended in water, oil, or in an atmosphere containing hydrogen, as they may forfeit their magnetic strength.
Advantages and disadvantages of neodymium magnets NdFeB.
Apart from their notable holding force, neodymium magnets have these key benefits:
- They do not lose their even over approximately ten years – the loss of power is only ~1% (theoretically),
- They show superior resistance to demagnetization from outside magnetic sources,
- In other words, due to the glossy gold coating, the magnet obtains an stylish appearance,
- The outer field strength of the magnet shows elevated magnetic properties,
- Thanks to their high temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C or more,
- With the option for tailored forming and precise design, these magnets can be produced in various shapes and sizes, greatly improving application potential,
- Key role in advanced technical fields – they serve a purpose in data storage devices, electric motors, healthcare devices along with other advanced devices,
- Thanks to their power density, small magnets offer high magnetic performance, with minimal size,
Disadvantages of neodymium magnets:
- They may fracture when subjected to a heavy impact. If the magnets are exposed to mechanical hits, we recommend in a metal holder. The steel housing, in the form of a holder, protects the magnet from fracture , and at the same time strengthens its overall durability,
- They lose power at high temperatures. Most neodymium magnets experience permanent reduction in strength when heated above 80°C (depending on the geometry 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 common to use sealed magnets made of rubber for outdoor use,
- Limited ability to create threads in the magnet – the use of a housing is recommended,
- Possible threat related to magnet particles may arise, in case of ingestion, which is notable in the context of child safety. Additionally, small elements from these magnets have the potential to complicate medical imaging when ingested,
- Due to expensive raw materials, their cost is considerably higher,
Handle with Care: 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. 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.
Neodymium magnets are highly delicate, they easily fall apart as well as can crumble.
Neodymium magnetic are fragile as well as will crack if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal and 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.
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 can become demagnetized at high temperatures.
Under specific conditions, Neodymium magnets may experience demagnetization when subjected to high temperatures.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times stronger, and their strength can surprise you.
Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional 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.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
Magnetic 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. Avoid placing neodymium magnets in close proximity to electronic devices.
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 significant injuries, and even death.
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.
If joining of neodymium magnets is not controlled, then they may crumble and crack. Remember not to approach them to each other or have them firmly in hands at a distance less than 10 cm.
Keep neodymium magnets away from GPS and smartphones.
Neodymium magnets generate intense magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
