Shopping tips

Handheld magnet separators with a grip can be utilized for diverse industrial uses, e.g. in sorting raw substances, cleaning production lines, or extracting iron within debris. They function due to a strong magnetic zone, produced by ferrite magnetic cores, placed in a housing containing a handle, which simplifies operation and improves precision during work.

Advantages and disadvantages of neodymium magnets NdFeB.

Besides their high retention, neodymium magnets are valued for these benefits:

  • They virtually do not lose power, because even after ten years, the performance loss is only ~1% (based on calculations),
  • They are highly resistant to demagnetization caused by external magnetic sources,
  • The use of a polished silver surface provides a eye-catching finish,
  • They exhibit superior levels of magnetic induction near the outer area of the magnet,
  • Thanks to their exceptional temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C or more,
  • With the option for fine forming and personalized design, these magnets can be produced in various shapes and sizes, greatly improving engineering flexibility,
  • Significant impact in modern technologies – they serve a purpose in computer drives, electric drives, diagnostic apparatus along with sophisticated instruments,
  • Relatively small size with high magnetic force – neodymium magnets offer impressive pulling strength in small dimensions, which allows for use in compact constructions

Disadvantages of rare earth magnets:

  • They can break when subjected to a sudden 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 damage and enhances its overall resistance,
  • Magnets lose field strength when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible performance loss (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,
  • Due to corrosion risk in humid conditions, it is common to use sealed magnets made of synthetic coating for outdoor use,
  • The use of a protective casing or external holder is recommended, since machining internal cuts in neodymium magnets is difficult,
  • Possible threat from tiny pieces may arise, if ingested accidentally, which is notable in the context of child safety. Additionally, minuscule fragments from these devices may complicate medical imaging when ingested,
  • High unit cost – neodymium magnets are costlier than other types of magnets (e.g., ferrite), which can restrict large-scale applications

Handle Neodymium Magnets with Caution

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.

Neodymium magnets should not be near people with pacemakers.

Neodymium magnets generate very strong magnetic fields that can 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.

Keep neodymium magnets away 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 damage videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

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 magnetic are highly delicate, they easily fall apart and can become 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.

Keep neodymium magnets away from GPS and smartphones.

Neodymium magnets generate intense magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets are among the strongest magnets on Earth. The surprising force they generate between each other can shock you.

To handle magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.

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.

Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

Neodymium magnets bounce and also clash mutually within a radius of several to almost 10 cm from each other.

 Keep neodymium magnets far from youngest 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.

Warning!
