The magnetic lines consist in circles round the connecting rods, while the lines of electric force and induction stretch between the two branches; each of these sets of lines vanishes in turn : the magnetic, when the balls are at their maxi- mvim difference of… … I 343] HERTZS EXPERIMENTS 417 then travels along it as a wave. It has already been said (341)that the velocity of propagation of energy through the ether is verygreat (3 x 10^^ cm. per second), but since the time period of the oscil-lations can be made exceedingly small, it is possible for the…
