Summary: | (1) A silica bulb, similar to those employed in the experiments describe at p. 214, ‘Roy. Soc. Proc.,’ A, vol. 81, was rotated four to five revolution per second; the degree of exhaustion was similar to that reached in the former experiments, the residual gas being oxygen. The inductor was charged gradually, until the bulb glowed; then slowly discharged through piece of damped thread, until the glow entirely died out; the graduate electroscope being observed during the slow discharge. On establishing the magnetic field, the brilliant glow was at once restored. This phenomenon could be repeated at any time with certainty. In some experiments the south pole was effective, the north pole not so. This was probably connected with the fact that the north pole deflected the glow away from the stem the bulb, which was the axis of rotation, and thus in contact with outside bodies. (2) A silica bulb, the residual gas being air, when similarly treated glowed; but the magnetic effect was less marked than when oxygen was the residual gas. |
