TOTAL FLUX through a solenoid

[K Dhiraj Bhak]

suppose a solenoid has N turns
What is the Flux through the Solenoid?

similarly if a coil has N turns , what is the flux through the whole coil?
i know how to find flux through a given AREA,,,like a coil with just 1 turn...

How do u find flux for the entire system?

Superposition principle: you add up the flux from each turn.
