That´s strange...i could not think of air as a conductor  |
The measurment was not done in air. It was done in the ground.
The vector current (I) was used as conductivity for electric field intensity. Affected also by tellurics, when a metal is buried, the streams run towards the metal, increasing the flow of electric current, hence the difference in value.
For a resistive object, it flows around it.
