How to effectively isolate electromagnetic interference between the coil and the magnetic core using a universal coil magnetic separator

Electromagnetic interference (EMI) between coils and magnetic cores is a common problem in electronic devices and systems. This interference not only affects the performance of the equipment, but may also lead to energy loss, signal distortion, and equipment failure. To effectively address this issue,Universal coil magnetic separatorWidely used in various electronic devices. This article will delve into the working principle and performance advantages of universal coil magnetic separators, and use the example analysis of the Research Platinum brand universal coil magnetic separator from Advanced Institute (Shenzhen) Technology Co., Ltd. to demonstrate its excellent effect in electromagnetic interference between the isolation coil and the magnetic core.

1、 The Causes and Effects of Electromagnetic Interference

When the coil is energized, it generates a magnetic field, and the magnetic core is magnetized, forming a magnetic circuit. When the current in the coil changes, the magnetic field also changes, resulting in electromagnetic interference. This interference not only affects the energy transfer between the coil and the magnetic core, but may also have adverse effects on other electronic devices around it, such as signal distortion, device misoperation, etc.

2、 Working principle of universal coil magnetic separator

Universal coil isolation sheet is a material specifically used to isolate electromagnetic interference between coils and magnetic cores. It usually has high magnetic permeability, high resistivity, and good absorption performance. When the coil is energized and generates a magnetic field, the magnetic separator can absorb and convert some of the magnetic field energy, thereby reducing the interference of the magnetic field on the magnetic core. Meanwhile,Magnetic separatorIt can also guide the magnetic field to propagate along a specific path, avoiding the magnetic field from spreading into the surrounding space and further reducing electromagnetic interference.
