DEVELOPS ELECTRIC EXCITATION. 35 



conducting wires wound in the corkscrew form 

 of a helix. The action of these currents is 

 more powerful than those about permanent steel 

 magnets. 



Current changers, or commutators, convert 

 vibrations into continuous currents in closed cir- 

 cuits, as previously described. 



The swift axial rotations of the planets opposite 

 to the excited globe of the sun, by inducing the 

 continual circulation of electric currents about 

 each one of them, convert them all into powerful 

 electro-magnets. Thus we have a solar system 

 with a vast central electro-magnet, and one hun- 

 dred and fifty electro-magnets revolving around it 

 each rotating on its axis. These act and react on 

 each other unceasingly, and with intense power, de- 

 veloping the phenomena of solar light and heat. 



THE ROTATION OF ALL BODIES OPPOSITE TO MAGNETS 

 INDUCES CIRCULATING ELECTRIC CURRENTS. 



Glass cylinders are used for exhibiting electric 

 excitation in preference to metallic plates, because 

 the particles of this compound substance, like 

 those of amber and other resins, do not allow of 

 the speedy diffusion of the excitation in every 

 direction. 



To prove that the rotation of all bodies near 

 magnets induces the disturbance of the electric 

 ether, and the transmission of action thereby, 

 Professor Faraday rotated a copper plate between
