The magnetic core is magnetized by the field, and its internal magnetic domain rotates slowly.When current is passed through the coil in Figure 1, the coil generates a magnetic field.To understand how an inductor becomes saturated, see Figure 1 and the steps for inductor saturation described below: This article will address how inductors become saturated, how saturation affects the circuit, and methods to detect inductor saturation. The saturation behavior of the inductor is often misunderstood and can be troublesome. There are many considerations to make when choosing an inductor, such as inductance value, DCR, size, and saturation current.
