Biot-Savart's law is used to determine in all regions of space the magnetic field generated by a finite length conducting tube of negligible thickness. Simplified approximate closed form solutions for the magnetic field in the tube axis vicinity, near the median plane just outside the tube, and very far from the tube, are also derived. Lastly, the finite tubular conductor results are used to address the finite solenoid magnetic field's azimuthal component.
