Problem
A long, straight vertical conductor coincides with the z-axis and carries a current of 15A upward.
(i) Determine the magnitude of the magnetic field at the point P(3.0cm,4.0cm,0).
(ii) State the direction of this magnetic field with respect to the coordinate axes.
(iii) If the current in the conductor were reversed in direction while keeping its magnitude the same, what would be the new direction of the magnetic field at P?
