Shopping tips

Magnetic holders with neodymium magnets featuring an external thread are modern solutions, used across various industries, including automotive, light industry, or assembly technology. Their design relies on a strong NdFeB magnet, embedded within a durable steel housing coated with zinc and nickel. Threaded pin ranging from M3–M10 enables installation into threaded holes, which makes it possible to screw in various components. Thanks to a focused magnetic field, such mounts provide a holding force from 3 to 68 kg, depending on. Applications of the holders include not only industrial operations and home installations. Some versions are equipped with a protective layer, which safeguards mounted elements from damage and increases grip. However, it is important to remember NdFeB magnets are brittle and may break under over-tightened mounting. Careful handling is advised, and they should be stored away from magnetic cards and electronic devices. For best quality, it is advisable to choose models from trusted manufacturers.

Advantages and disadvantages of neodymium magnets NdFeB.

In addition to their remarkable pulling force, neodymium magnets offer the following advantages:

  • Their power is durable, and after approximately 10 years, it drops only by ~1% (theoretically),
  • They protect against demagnetization induced by ambient electromagnetic environments very well,
  • In other words, due to the metallic silver coating, the magnet obtains an stylish appearance,
  • They possess strong magnetic force measurable at the magnet’s surface,
  • Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C or more,
  • With the option for customized forming and personalized design, these magnets can be produced in numerous shapes and sizes, greatly improving engineering flexibility,
  • Wide application in new technology industries – they find application in computer drives, electric drives, clinical machines or even high-tech tools,
  • Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications

Disadvantages of neodymium magnets:

  • They may fracture when subjected to a strong impact. If the magnets are exposed to shocks, it is suggested to place them in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from damage and enhances its overall strength,
  • They lose magnetic force at extreme temperatures. Most neodymium magnets experience permanent decline in strength when heated above 80°C (depending on the geometry and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
  • They rust in a damp environment, especially when used outside, we recommend using moisture-resistant magnets, such as those made of rubber,
  • The use of a protective casing or external holder is recommended, since machining fine details in neodymium magnets is restricted,
  • Health risk from tiny pieces may arise, when consumed by mistake, which is notable in the health of young users. Furthermore, minuscule fragments from these products can hinder health screening when ingested,
  • Higher purchase price is one of the drawbacks compared to ceramic magnets, especially in budget-sensitive applications

Caution with Neodymium Magnets

Magnets made of neodymium are incredibly delicate, they easily fall apart and can crumble.

Neodymium magnets are extremely fragile, and by joining them in an uncontrolled manner, they will crack. Neodymium magnets are made of metal and coated with a shiny nickel, but they are not as durable as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.

You should keep neodymium magnets at a safe distance from the wallet, computer, and TV.

The strong magnetic field generated by neodymium magnets can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

People with pacemakers are advised to avoid neodymium magnets.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.

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.

  Neodymium magnets should not be around 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.

Neodymium magnets can become demagnetized at high temperatures.

Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.

Never bring neodymium magnets close to a phone and GPS.

Neodymium magnets generate strong magnetic fields that interfere with magnetometers and compasses 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.

If you have a finger between or alternatively on the path of attracting magnets, there may be a serious cut or a fracture.

Dust and powder from neodymium magnets are highly 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 most powerful magnets ever invented. Their power can shock 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.

Be careful!
