# Solenoid Coil with AC current

Hello
I want to calculate field of the Solenoid Coil with AC current.
For a DC current field is calculated easily from the BiotSavart.
What is the process for AC current?
Get the L value with RLCMeter in operating frequency?
Is there an equation to get the field with inductance?(H=$\frac{NI}{L}$)?
The equation is true for AC current?
Should I put the RMS value in the equation? [ or i=I sin(ωt) ]
