Why does the chip inductor produce a magnetic field?
Any current of the chip inductor in the circuit will generate a magnetic field, and the magnetic flux of the magnetic field will act on the circuit. When the current passing through the chip inductor changes, the DC voltage potential generated in the chip inductor will prevent the current from changing. When the current passing through the inductor coil increases, the self-induced electromotive force and electricity generated by the inductor coil. When the current passing through the inductor coil decreases, the self-induced electromotive force is in the same direction as the current, preventing the current from decreasing and releasing the stored energy at the same time.

Compensation for the decrease in current. The direction of flow is opposite to prevent the increase of current, and at the same time, part of the electric energy is converted into magnetic field and stored in the inductor; therefore, after inductance filtering, not only the pulsation of load current and voltage is reduced, the waveform becomes smooth, and the rectifier diode is turned on. The angle increases.
