Shopping tips

The openings on the mounting sheet enable easy mounting onto a surface, allowing for a secure fixing using bolts, which also enhances the adaptability of use, for example in brackets for tools or covers of machines.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:

  • They have constant strength, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
  • Their ability to resist magnetic interference from external fields is impressive,
  • The use of a decorative gold surface provides a eye-catching finish,
  • Magnetic induction on the surface of these magnets is very strong,
  • With the right combination of compounds, they reach excellent thermal stability, enabling operation at or above 230°C (depending on the form),
  • The ability for precise shaping and adjustment to individual needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which amplifies their functionality across industries,
  • Key role in cutting-edge sectors – they find application in hard drives, rotating machines, diagnostic apparatus and other advanced devices,
  • Compactness – despite their small size, they generate strong force, making them ideal for precision applications

Disadvantages of NdFeB magnets:

  • They can break when subjected to a sudden impact. If the magnets are exposed to external force, we recommend in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from breakage , and at the same time increases its overall robustness,
  • High temperatures may significantly reduce the holding force of neodymium magnets. Typically, above 80°C, they experience permanent weakening in performance (depending on shape). 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 wise to use sealed magnets made of plastic for outdoor use,
  • The use of a protective casing or external holder is recommended, since machining internal cuts in neodymium magnets is difficult,
  • Safety concern from tiny pieces may arise, in case of ingestion, which is crucial in the protection of children. Moreover, minuscule fragments from these magnets may complicate medical imaging once in the system,
  • High unit cost – neodymium magnets are more expensive than other types of magnets (e.g., ferrite), which increases the cost of large-scale applications

Highest magnetic holding forcewhat it depends on?

The given holding capacity of the magnet means the highest holding force, determined in the best circumstances, namely:

  • using a steel plate with low carbon content, acting as a magnetic circuit closure
  • with a thickness of minimum 10 mm
  • with a polished side
  • with no separation
  • with vertical force applied
  • at room temperature

Practical aspects of lifting capacity – factors

In practice, the holding capacity of a magnet is conditioned by the following aspects, from crucial to less important:

  • Air gap between the magnet and the plate, as even a very small distance (e.g. 0.5 mm) can cause a drop in lifting force of up to 50%.
  • Direction of applied force, because the maximum lifting capacity is achieved under perpendicular application. The force required to slide the magnet along the plate is usually several times lower.
  • Thickness of the plate, as a plate that is too thin causes part of the magnetic flux not to be used and to remain wasted in the air.
  • Material of the plate, because higher carbon content lowers holding force, while higher iron content increases it. The best choice is steel with high magnetic permeability and high saturation induction.
  • Surface of the plate, because the more smooth and polished it is, the better the contact and consequently the greater the magnetic saturation.
  • Operating temperature, since all permanent magnets have a negative temperature coefficient. This means that at high temperatures they are weaker, while at sub-zero temperatures they become slightly stronger.

* Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance {between} the magnet’s surface and the plate reduces the lifting capacity.

Caution with Neodymium Magnets

Avoid bringing neodymium magnets close to a phone or GPS.

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

  Do not give neodymium magnets to youngest children.

Not all neodymium magnets are toys, so do not let children play with them. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.

Magnets made of neodymium are highly delicate, they easily crack 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.

Neodymium magnets are the most powerful magnets ever invented. Their strength can shock you.

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.

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

The magnet is coated with nickel. Therefore, exercise caution 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.

Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.

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 devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from 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 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 are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

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

Be careful!
