Topband: An experience with "DR. GAUSS"

[N7DF]

My son did a Science Fair project using a "Dr. Gauss" EMF detector ( http://www.johnleemd.com/store/more_gauss.html ) and we discovered that we could detect my buried coax from the 60 Hz EMF that the Dr. Gauss could detect along its length.  Even when the coax was disconnected from the radio we could get a reading.
   
  Apparently the above ground section of the coax shield is picking up the powerline emissions and carrying them along its length, even underground. 
   
  It was also informative to trace the wires in the house and see how the EMF fields vary throughout the building.  Also we found pieces of aluminum pipe buried in the snow by their reradiated 60 Hz EMF.  Chain link fences make it go wild!
   
  These detectors are intended for  60Hz but do work at RF to some extent.
