An Inductive Curio

Whilst leaning on the gate below, trying to take a shot of the sunset, I received an electric shock. My immediate reaction was surprise at having built a static charge, but I thought no more of it; only as I leant back onto the metal — and was shocked again — did I realise that the cause was not the transfer of charge through friction, but something much more remarkable.

The gate and the power lines are simply acting as per faraday’s experiment predicts, the alternating electric field in the wires is inducing an alternating magnetic field which in turn is causing eddy currents in the gate.

I returned at dawn and managed to capture a picture of the spark:

Further testing to follow!
