This article provides overview of common and less common inductor and transformer symbols.

The inductors, coils or chokes are electrical passive components that have a certain number of turns of wire that introduce magnetic inductance to an electrical circuit to produce a magnetic flux or to mechanically react to magnetic flux variations.

There are many types of inductors available depending to its core type, leads, shileding, number of windings, variability etc. See overview of most often used fixed and variable inductor and transformer symbols.
