Magnetic field coupling:A magnetic field will be generated around any current-carrying conductor.When the current changes,an alternating magnetic field will be generated.The magnetic field will inevitably generate an induced potential in the closed loop around it and cause interference.It is coupled through the mutual inductance between the conductors.Inside the device,the leakage magnetic field of the coil or transformer can also cause interference;outside the device,two wires running in parallel can also cause interference.Electromagnetic radiation can cause magnetic field coupling interference.For example,when a high-frequency current flows through a conductor,electromagnetic waves that propagate into space are generated around the conductor.These disturbances are easily coupled into the computer through power lines and long signal lines.In addition,long-line interference has an antenna effect,that is,it can radiate interference waves and receive interference waves.
磁场耦合：在任何载流导体周围都会产生磁场，当电流变化时会产生交变磁场，该磁场必然会在其周围的闭合回路中产生感应电势引起干扰，它是通过导体间互感耦合进来的。在设备内部，线圈或变压器的漏磁也会引起干扰；在设备外部，平行架设的两根导线也会产生干扰。电磁辐射会造成磁场耦合干扰，如高频电流流过导体时，在该导体周围便产生了向空间传播的电磁 波。这些干扰极易通过电源线和长信号线耦合到计算机中。另外，长线干扰具有天线效应，即能够辐射干扰波和接受干扰波。
