Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Moreover, even though neodymium is part of the strongest magnets, they are susceptible to corrosion in humid environments. Therefore, they are coated with a thin layer of nickel to protect them from corrosion. It's worth noting 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 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, as well as in water or oil. Additionally, they can distort 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 coatings, such as gold, to shield them from environmental factors and extend their lifespan. High temperatures exceeding 130°C can result in a loss of their magnetic properties, although there are particular types of neodymium magnets that can tolerate temperatures up to 230°C.
As for potential dangers, 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 environment containing hydrogen, as they may lose their magnetic properties.
Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
In addition to immense strength, neodymium magnets have the following advantages:
- They do not lose their power (of the magnet). After about 10 years, their power decreases by only ~1% (theoretically),
- They are highly resistant to demagnetization by external magnetic field,
- Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
- They have exceptionally high magnetic induction on the surface of the magnet,
- Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C and above...
- The ability for precise shaping or customization to specific needs – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
- Significant importance in the industry of new technologies – are used in HDD drives, electric motors, medical devices and other modern machines.
Disadvantages of neodymium magnets:
- They are fragile when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts, and at the same time increases its overall strength,
- High temperatures can reduce the strength of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent reduction in strength (although it is dependent on the shape and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
- Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
- The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
- Possible danger arising from small pieces of magnets are risky, if swallowed, which is particularly important in the context of child safety. It's also worth noting that miniscule components of these devices have the potential to be problematic in medical diagnosis after entering the body.
Be Cautious with Neodymium Magnets
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 will attract each other within a distance of several to about 10 cm from each other. Don't put your fingers in the path of magnet attraction, as a significant injury may occur. Depending on how huge the neodymium magnets are, they can lead to a cut or alternatively a fracture.
The magnet coating is made of nickel, so be cautious if you have an 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Keep neodymium magnets away from GPS and smartphones.
Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Do not give neodymium magnets to 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.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
Neodymium magnets produce strong magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Neodymium magnets can become demagnetized at high temperatures.
Despite the fact that 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.
Dust and powder from neodymium magnets are flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. 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.
Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional damage to the magnets.
Magnets made of neodymium are fragile and can easily crack as well as shatter.
Magnets made of neodymium are delicate 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. At the moment of connection between the magnets, small sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.
Neodymium magnets should not be near people with pacemakers.
Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.
