Magnetic Field From a Solenoid - Biot-Savart Law

[fonz]

I'm fairly confident I can express the strength of a magnetic field along the axis of a current carrying loop at some distance x away using the Biot-Savart Law. I'm just trying to extend this idea for a solenoid with N turns. I'm assuming that the current would become NI in this case?

Only if the coils lay atop one another.

The proper way is to integrate I along the helical path of the solenoid winding.
