How to wind an inductor
Would there be cancellation of the inductance value


Picture the current in a single turn of wire. Let's say the current is 1 amp travelling clockwise at a particular moment in time. If you have two turns wound the same direction, then the currents in each wire are both travelling clockwise. 

You have created a magneto motive force (MMF) of 2 ampere-turns with those two wires each carrying 1 amp. That MMF could equally have been created with 1 wire carrying 2 amps or a thousand wires carrying 2 mA. The magnetic field produced would be identical.

Now, if you picture one turn carrying current counter-clockwise, its magnetic field would cancel one turn carrying the same current in a clockwise direction.

So, providing the currents are all travelling in the same direction around a common centreline then there will be no cancellation of either magnetic field or inductance.
