AN ETHER DISTURBANCE AROUND AN ELECTRON CURRENT 



In the left-hand photograph an electric current is passing through the coil, thus producing a magnetic field and transforming the poker 

 into a magnet. The poker is then able to support a pair of scissors. As soon as the electric current is broken off, as in the second photo- 

 graph, the ether disturbance ceases. The poker loses its magnetism, and the scissors fall.
