Are 6x2mm disc magnets affected by magnetic shielding materials?

Oct 13, 2025|

As a supplier of 6x2mm Disc Magnets, I often encounter inquiries from customers about the impact of magnetic shielding materials on these small yet powerful magnets. In this blog post, I will delve into the science behind magnetic shielding and explore whether 6x2mm disc magnets are affected by such materials.

Understanding 6x2mm Disc Magnets

Before we discuss the effects of magnetic shielding, let's first understand the characteristics of 6x2mm disc magnets. These magnets are typically made of neodymium, a rare - earth material known for its strong magnetic properties. With a diameter of 6mm and a thickness of 2mm, they are compact and can generate a relatively high magnetic field for their size. They are widely used in various applications, such as electronics, jewelry making, and scientific experiments.

What is Magnetic Shielding?

Magnetic shielding is the process of reducing the magnetic field in a specific area by using materials that can redirect or absorb the magnetic flux. The basic principle behind magnetic shielding is that certain materials, such as mu - metal (an alloy of nickel, iron, and other elements), have high magnetic permeability. Magnetic permeability is a measure of how easily a material can be magnetized. When a magnetic field encounters a material with high magnetic permeability, the magnetic field lines tend to pass through the shielding material rather than the surrounding space, effectively reducing the magnetic field in the shielded area.

How Do Magnetic Shielding Materials Work?

There are two main types of magnetic shielding materials: passive and active. Passive shielding materials, like mu - metal and iron, work by providing a low - reluctance path for the magnetic field lines. When a magnet is placed near a passive shielding material, the magnetic field lines are attracted to the material and flow through it, creating a magnetic circuit that diverts the field away from the protected area.

Active shielding, on the other hand, uses electromagnets to generate a magnetic field that cancels out the external magnetic field. This method is more complex and is often used in high - precision applications where a very low magnetic field environment is required.

Are 6x2mm Disc Magnets Affected by Magnetic Shielding Materials?

The short answer is yes, 6x2mm disc magnets can be affected by magnetic shielding materials. The degree of the effect depends on several factors, including the type of shielding material, its thickness, and the distance between the magnet and the shielding material.

Type of Shielding Material

As mentioned earlier, materials with high magnetic permeability, such as mu - metal, are more effective at shielding magnetic fields. If a 6x2mm disc magnet is placed near a sheet of mu - metal, a significant portion of the magnetic field lines will be redirected through the mu - metal, reducing the magnetic field strength in the surrounding area. In contrast, materials with low magnetic permeability, like plastic or wood, have little to no effect on the magnetic field of the disc magnet.

Thickness of the Shielding Material

The thickness of the shielding material also plays an important role. Generally, thicker shielding materials provide better shielding performance. For a 6x2mm disc magnet, a thin sheet of mu - metal may only partially shield the magnetic field, while a thicker sheet can provide more complete shielding. However, increasing the thickness also increases the cost and weight of the shielding solution.

Distance between the Magnet and the Shielding Material

The closer the 6x2mm disc magnet is to the shielding material, the more effective the shielding will be. As the distance between the magnet and the shielding material increases, the magnetic field lines have more space to spread out, and the shielding material has less influence on the magnetic field.

Applications of Magnetic Shielding for 6x2mm Disc Magnets

There are several applications where magnetic shielding for 6x2mm disc magnets is necessary. For example, in electronic devices, these magnets can interfere with the operation of sensitive components, such as sensors and circuits. By using magnetic shielding materials, the magnetic field of the disc magnets can be contained, preventing interference with other parts of the device.

In scientific experiments, magnetic shielding can be used to create a controlled magnetic field environment. This is especially important in experiments that require precise measurements of magnetic fields or where the presence of external magnetic fields can affect the results.

Other Disc - Shaped Magnets and Shielding

Our company also offers other disc - shaped magnets, such as the 4mm X 2mm Disc Magnet. Similar to the 6x2mm disc magnets, these smaller magnets can also be affected by magnetic shielding materials. The principles of magnetic shielding apply equally to all disc - shaped magnets, regardless of their size.

Conclusion

In conclusion, 6x2mm disc magnets can be affected by magnetic shielding materials. The effectiveness of the shielding depends on the type, thickness, and distance of the shielding material from the magnet. Understanding the principles of magnetic shielding is crucial for applications where the magnetic field of these magnets needs to be controlled.
