Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their exceptional pulling force, neodymium magnets offer the following advantages:
- They do not lose their power nearly 10 years – the reduction of lifting capacity is only ~1% (according to tests),
- They remain magnetized despite exposure to magnetic surroundings,
- In other words, due to the metallic nickel coating, the magnet obtains an professional appearance,
- They possess intense magnetic force measurable at the magnet’s surface,
- These magnets tolerate extreme temperatures, often exceeding 230°C, when properly designed (in relation to form),
- The ability for accurate shaping or adaptation to custom needs – neodymium magnets can be manufactured in multiple variants of geometries, which extends the scope of their use cases,
- Significant impact in cutting-edge sectors – they are utilized in HDDs, electric drives, healthcare devices and other advanced devices,
- Thanks to their power density, small magnets offer high magnetic performance, with minimal size,
Disadvantages of neodymium magnets:
- They are prone to breaking when subjected to a powerful impact. If the magnets are exposed to external force, we recommend in a steel housing. The steel housing, in the form of a holder, protects the magnet from breakage while also reinforces its overall resistance,
- Magnets lose pulling force when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible power drop (influenced by the magnet’s form). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
- They rust in a damp environment. For outdoor use, we recommend using moisture-resistant magnets, such as those made of rubber,
- Using a cover – such as a magnetic holder – is advised due to the challenges in manufacturing complex structures directly in the magnet,
- Possible threat related to magnet particles may arise, when consumed by mistake, which is crucial in the family environments. It should also be noted that miniature parts from these magnets can hinder health screening if inside the body,
- Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications
Caution with Neodymium Magnets
You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.
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.
Do not bring neodymium magnets close to GPS and smartphones.
Strong fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
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.
Neodymium magnets are the strongest magnets ever invented. Their strength can surprise 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 will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
Magnets will attract each other within a distance of several to around 10 cm from each other. Remember not to place fingers between magnets or in their path when attract. Magnets, depending on their size, are able even cut off a finger or there can be a serious pressure or even a fracture.
Neodymium magnets are not recommended for 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.
Magnets made of neodymium are noted for being fragile, which can cause them to become damaged.
Neodymium magnets are characterized by significant fragility. Magnets made of neodymium are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of connection between the magnets, sharp metal fragments can be dispersed in different directions.
The magnet is coated with nickel - be careful 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.
Magnets should not be treated as toys. Therefore, it is not recommended for youngest children to have access to them.
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.
Neodymium magnets can become demagnetized at high temperatures.
Despite the general resilience of magnets, 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.
Exercise caution!
