Why does the inductor have no positive and negative poles?

In most cases, the inductor is a coil (it can be a piece of wire at UHF). When it is used alone, it does not show its polarity, that is, there is no difference between you and the reverse connection.
Even if the inductor series is connected in parallel, because the strong magnetic induction area of the inductor is particularly limited to the local area near the two ends, the inductance mutual inductance is limited, so the polarity is usually not indicated. Of course, if you find a connection in the actual circuit, you can reverse it or change the position to try. If you use two larger inductors like a solenoid, pay attention to their polarity.
