Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
Apart from their superior magnetic energy, neodymium magnets have these key benefits:
- They virtually do not lose strength, because even after ten years, the decline in efficiency is only ~1% (in laboratory conditions),
- They remain magnetized despite exposure to magnetic noise,
- Because of the reflective layer of gold, the component looks visually appealing,
- Magnetic induction on the surface of these magnets is notably high,
- These magnets tolerate extreme temperatures, often exceeding 230°C, when properly designed (in relation to form),
- With the option for customized forming and targeted design, these magnets can be produced in various shapes and sizes, greatly improving application potential,
- Key role in advanced technical fields – they are used in HDDs, electromechanical systems, healthcare devices as well as technologically developed systems,
- Thanks to their concentrated strength, small magnets offer high magnetic performance, while occupying minimal space,
Disadvantages of rare earth magnets:
- They may fracture when subjected to a powerful impact. If the magnets are exposed to mechanical hits, it is advisable to use in a steel housing. The steel housing, in the form of a holder, protects the magnet from fracture while also increases its overall durability,
- Magnets lose magnetic efficiency when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible performance loss (influenced by the magnet’s profile). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
- Due to corrosion risk in humid conditions, it is advisable to use sealed magnets made of protective material for outdoor use,
- The use of a protective casing or external holder is recommended, since machining fine details in neodymium magnets is difficult,
- Safety concern from tiny pieces may arise, when consumed by mistake, which is significant in the context of child safety. It should also be noted that small elements from these assemblies can disrupt scanning once in the system,
- 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 become demagnetized at high temperatures.
Whilst Neodymium magnets can lose their magnetic properties 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.
The magnet coating contains nickel, so be cautious 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, you can try wearing gloves or simply avoid direct contact with nickel-plated 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 injuries.
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 major injury may occur. Magnets, depending on their size, can even cut off a finger or there can be a severe 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.
Keep neodymium magnets as far away as possible from GPS and smartphones.
Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.
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.
Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.
The strong magnetic field generated by neodymium magnets 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 videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
Neodymium magnets should not be around youngest children.
Neodymium magnets are not toys. You cannot allow them to become toys for children. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their power 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 disruption to the magnets.
Magnets made of neodymium are highly delicate, they easily crack 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 as well as coated with a shiny nickel plating, they are not as hard as steel. At the moment of collision between the magnets, tiny sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
