This figure indicates the directions of the current in one turn of a long, tightly-packed solenoid that is horizontal.
What is the direction of the magnetic field inside the solenoid?
a) leftward
b)rightward
Can someone please explain this? The textbook explanation is NOT clear to me. Thank you!

Shown in the figure below is a long solenoid. Your solenoid has N loops, a length of L, and is carrying a current of I. We shall use the "long" approximation for which the field outside the solenoid is very very small compared to the field inside the solenoid.
