Abstract :
The derivation of a magnetic flux-density vector Boarr from Ampere´s law requires additional symmetry and field-line arguments to be complete, if the more complicated Biot-Savart law is to be avoided in undergraduate text treatments. A widespread reason for a zero radial component Boarr of due to an infinite straight current is refuted.
