An inductor is characterized by its inductance which is the ratio of the voltage to the rate of change of current.

Inductor with polarity. You are in essence choosing which end to place the red lead of your voltmeter. Transformers are said to have additive or subtractive polarity based on their physical arrangement of terminals and the polarity of windings connected to the terminals. When you label one terminal of the inductor with a plus sign youre simply choosing a reference polarity.

As a result inductors oppose any changes in current through them. On rare occasions it has been reported that some inductors perform better when mounted in one particular orientation due to interaction with nearby components or ground plane conductors. Bond polarity is the polarity particular bond within a molecule while molecular polarity is the polarity of the whole molecule.

If you calculate that the voltage across the inductor is negative then you know the absolute polarity is opposite the chosen reference polarity. Basic facts about inductors lesson 6 why is there a direction mark on inductors. Unlike capacitors or diodes inductors do not have a functional polarity and work equally in either direction so polarity is not important in the vast majority of end use circuits.

The inductor itself doesnt have polarity however if you have several of these very close together their generated magnetic fields can interact like transformers so knowing the polarity would be useful to design around that or cancel the effects. Take for example water h20. The convention used for north american transformers is that facing the high voltage side of the transformer the h1 terminal is on the observers right.

Why is there a direction mark on inductors sometimes there is a mark on. According to lenzs law the induced voltage has a polarity direction which opposes the change in current that created it.
