Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their pulling strength, neodymium magnets provide the following advantages:
- They virtually do not lose strength, because even after 10 years, the decline in efficiency is only ~1% (in laboratory conditions),
- They show superior resistance to demagnetization from external magnetic fields,
- Thanks to the shiny finish and gold coating, they have an aesthetic appearance,
- They exhibit superior levels of magnetic induction near the outer area of the magnet,
- These magnets tolerate high temperatures, often exceeding 230°C, when properly designed (in relation to profile),
- Thanks to the possibility in shaping and the capability to adapt to individual requirements, neodymium magnets can be created in different geometries, which increases their usage potential,
- Wide application in advanced technical fields – they find application in computer drives, electric motors, healthcare devices or even other advanced devices,
- Relatively small size with high magnetic force – neodymium magnets offer intense magnetic field in small dimensions, which makes them useful in miniature devices
Disadvantages of rare earth magnets:
- They can break when subjected to a heavy impact. If the magnets are exposed to mechanical hits, it is advisable to use in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from fracture and additionally strengthens its overall resistance,
- High temperatures may significantly reduce the magnetic power of neodymium magnets. Typically, above 80°C, they experience permanent weakening in performance (depending on form). To prevent this, we offer heat-resistant magnets marked [AH], capable of working up to 230°C, which makes them perfect for high-temperature use,
- Due to corrosion risk in humid conditions, it is common to use sealed magnets made of protective material for outdoor use,
- Limited ability to create internal holes in the magnet – the use of a housing is recommended,
- Possible threat linked to microscopic shards may arise, especially if swallowed, which is crucial in the health of young users. Furthermore, miniature parts from these products might 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
Handle with Care: 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 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, can even cut off a finger or alternatively there can be a severe pressure or a fracture.
Maintain neodymium magnets far from 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.
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.
The magnet coating is made of nickel, so be cautious if you have an 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.
Dust and powder from neodymium magnets are highly 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 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.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
Neodymium magnets generate strong magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also damage videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.
Neodymium magnets are the strongest, most remarkable magnets on the planet, and the surprising force between them can shock you at first.
On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.
Neodymium magnets are delicate as well as can easily break as well as get damaged.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. 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.
Neodymium magnets can demagnetize at high temperatures.
Whilst Neodymium magnets can demagnetize at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.
Caution!
So that know how powerful neodymium magnets are and why they are so dangerous, see the article - Dangerous very strong neodymium magnets.
