The influence mechanism of the thickness of high permeability and low loss magnetic isolation sheets on magnetic resistance and isolation effect

With the development of electronic technology, electromagnetic compatibility (EMC) has become one of the key factors that designers must consider. Especially in the fields of high-frequency circuits, wireless communication, and precision instruments, effective magnetic shielding can prevent external magnetic fields from interfering with the operation of internal circuits, while also suppressing the adverse effects of self generated magnetic fields on the outside world. Therefore, it becomes particularly important to choose suitable magnetic shielding materials and understand their characteristics.High permeability and low loss magnetic isolation sheetIt has received widespread attention due to its excellent magnetic properties.

The relationship between the thickness of the magnetic separator and the magnetic resistance

• Reduce magnetic resistance: Thicker magnetic separators can provide a larger cross-section for magnetic flux lines to pass through, reducing magnetic resistance and allowing more magnetic flux to pass through the material itself rather than bypassing it, improving magnetic shielding efficiency.

• Enhanced magnetic isolation effect: As the thickness increases, the material's ability to block magnetic fields also increases accordingly, because thicker layers can accommodate more guided magnetic flux, reducing the possibility of leakage into external space.

However, it should be noted that thicker magnetic separators are not necessarily better. Thick magnetic separators may lead to increased costs, increased weight, and decreased flexibility. Therefore, in practical applications, it is necessary to find a balance point to meet specific needs while maintaining the best cost-effectiveness.

Principle of magnetic isolation

The main function of a magnetic separator is to redirect the magnetic field so that it propagates along the interior of the material rather than penetrating the material or diffusing into the surrounding environment. This process relies on the high magnetic conductivity and low loss characteristics of the material, which means that the material can efficiently conduct magnetic flux without generating excessive thermal energy loss.

The impact of thickness variation

• Improving magnetic isolation efficiency: Increasing the thickness of the magnetic isolation sheet appropriately can significantly enhance its magnetic isolation effect. This is because thicker layers provide more pathways to disperse and absorb incoming magnetic field energy, thereby reducing the amount of leakage.

• Improving edge effect: Thicker magnetic separators help alleviate edge effect, which refers to the local increase in magnetic field strength caused by the concentration of magnetic field at the material edge. This not only enhances the overall magnetic isolation performance, but also avoids potential hot spot issues.

However, it should also be noted that excessive pursuit of thickness can bring unnecessary burdens, such as increasing volume and weight. In addition, the optimal thickness may vary in different application scenarios and needs to be adjusted according to specific requirements.
