The influence of thickness of high permeability and low loss magnetic isolation sheet on its magnetic isolation effect

In modern electronic devices and communication systems, magnetic separators are widely used as a key component to reduce electromagnetic interference, improve system performance and stability. High permeability and low loss magnetic separators have become the preferred material in many fields due to their excellent magnetic permeability and low loss characteristics. This article will explore in depthHigh permeability and low loss magnetic isolation sheetThe influence of thickness on its magnetic isolation effect, and the introduction of the research platinum brand magnetic isolation sheet produced by Advanced Institute (Shenzhen) Technology Co., Ltd.

Basic principle of magnetic separator

Magnetic separators mainly achieve magnetic isolation by guiding and concentrating magnetic field lines through their high magnetic permeability characteristics, reducing magnetic field leakage. When a magnetic field encounters a high permeability material, the magnetic field lines tend to propagate along the interior of the material, thereby reducing electromagnetic interference to the surrounding environment.

The influence of the thickness of the magnetic separator

1. Magnetic resistance variation

Magnetic separatorThe thickness directly affects its magnetic resistance. Magnetic resistance is the resistance encountered when a magnetic field propagates in a material, which is related to the material's magnetic permeability and thickness. Generally speaking, as the thickness of the magnetic separator increases, the magnetic resistance also increases, making it more difficult for the magnetic field to penetrate the separator and enhancing the magnetic isolation effect.

2. Saturation effect

However, as the thickness of the magnetic separator increases, saturation effects may occur. When the magnetic field strength exceeds a certain value, the magnetic permeability of the magnetic separator will sharply decrease, resulting in an increase in magnetic field penetration ability and a decrease in magnetic isolation effect. Therefore, when designing magnetic separators, it is necessary to comprehensively consider the saturation magnetic induction strength of the material and the magnetic field strength in practical applications.

3. Eddy current losses

Thicker magnetic separators may generate significant eddy current losses in alternating magnetic fields. Eddy current loss is caused by magnetic field changes that induce currents (eddy currents) inside a conductor. These currents generate heat when flowing in the conductor, thereby consuming magnetic field energy. For high permeability materials, eddy current losses may be particularly significant, affecting the magnetic isolation effect and increasing the temperature rise of the material.

4. Trade offs in practical applications

In practical applications, the thickness of the magnetic separator needs to be balanced according to specific requirements. Although thinner magnetic separators have lower magnetic resistance, they may not provide sufficient magnetic isolation effect; Although thicker magnetic separators have good magnetic isolation effects, they may cause saturation effects and eddy current losses. Therefore, when selecting the thickness of the magnetic separator, it is necessary to comprehensively consider factors such as the electromagnetic environment, performance requirements, and cost of the system.
