Interesting. Assuming a plane wave sweeping broadside, with the field being the same at every point along the wire, one might be inclined to argue that the voltage induced on a wire should be the same at every point along a finite length. The "rise" in voltage as the field sweeps past would be with respect to time, rather than with respect to position. Sort of explains why a radio receiver works just fine with only one wire attached when you think about it. ;-) The Earth's (static) electric field is about 120 V/m at ground level on a stormless day. Better not walk too fast. Jogging might be fatal! Roy Lewallen, W7EL |
