Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
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 nickel to increase their durability. It's worth noting 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. They should not be used 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 conditions of high humidity. Therefore, they are often covered with thin coatings, such as gold, to protect them from environmental factors and prolong their durability. 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 conditions, 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 forfeit their magnetic strength.

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 approximately 10 years, their strength decreases by only ~1% (theoretically),
- They are exceptionally resistant to demagnetization caused by an external magnetic field,
- By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
- They possess very high magnetic induction on the surface of the magnet,
- Magnetic neodymium magnets are characterized by very high magnetic induction on the surface of the magnet and can operate (depending on the shape) even at temperatures of 230°C or higher...
- The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in various forms and dimensions, which amplifies their universality in usage.
- Key role in advanced technologically fields – find application in HDD drives, electric drive mechanisms, medical devices and various technologically advanced devices.
Disadvantages of neodymium magnets:
- They can break as they are extremely fragile when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts and also 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 loss in strength (although it is dependent on the form 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,
- They rust in a humid environment - during outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
- The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
- Potential hazard associated with microscopic parts of magnets can be dangerous, in case of ingestion, which is crucial in the context of children's health. It's also worth noting that small elements of these products can complicate diagnosis when they are in the body.
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 incredibly delicate, they easily crack and can crumble.
Neodymium magnets 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. 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 can demagnetize at high temperatures.
Although magnets are generally resilient, their ability to maintain their magnetic potency can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
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.
Never bring neodymium magnets close to a phone and GPS.
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.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
Magnets may crack or alternatively crumble with careless joining to each other. You can't move them to each other. At a distance less than 10 cm you should have them very strongly.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
Neodymium magnets generate strong magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also destroy devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Avoid contact with neodymium magnets 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their strength 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.
Maintain neodymium magnets far from children.
Remember that 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.
