B = μ_{0}NI for field inside solenoid...

how should i go about finding the field let say... 10cm away from one end of the solenoid

1. directly at the z-axis

2. not directly at the z-axis

this is assuming the solenoid has finite length, finite number of turns ,finite radius

(ex. L = 25cm , R = 10cm, N = 1000, I = 1A)

Please help me out hehe thx
