These interconnections of inductors produce more complex networks whose overall inductance is a combination of the individual inductors. However, there are certain rules for connecting inductors in series or in parallel and these are based on the fact that there is no mutual inductance or magnetic coupling between the individual inductors.
It is said that the inductors are connected in "Series" when they are connected in a straight line chain, from end to end. In the tutorial Resistors in Series we saw that the different values of the resistors connected together in series simply "aggregate" together and this is also true for the inductance. The series inductors are simply "aggregated together" because the number of turns of the coil is effectively increased, with the total inductance of the circuit LT that is equal to the sum of all the individual inductances added together.
