Consider a long (practically infinite) straight wire of radius, a, carrying a steady current that is uniformly distributed over its cross section as shown in the figure. Which of the following is FALSE? Contour C₂ for r₂a (a) Cylindrical wire (b) Wire cross section Contour C₁ for ra B © The magnitude of the magnetic field intensity, H, inside the wire is proportional to the distance,,, from the wire axis. The magnitude of the magnetic field intensity, H, on the surface of the wire (ra) is inversely proportional to a². The magnitude of the magnetic field intensity, H, outside the wire is inversely proportional to the distance, r, from the wire axis. The magnitude of the magnetic field intensity, H, outside the wire is proportional to the current, 7, on the wire.
