A solenoid of length 0.4 m and diameter 0.6 m consists of a single layer of 1000 turns of fine wire carrying a current of 5 x 10-3 A. Calculate the magnetic field strength on the axis at the middle and at the ends of the solenoid.
I know the field inside a long solenoid, B = μNI, which is unfortunately not applicable here. I tried it, but the answer was not matching, by a long distance.
Answers:
1.) π/√13 × 10-5 T
2.) 2π × 10-6 T
