To quickly assess the difficulty of the text, read a short excerpt:
Current of Air. — Arrange a rather short discharge, and while it is passing blow a stream of air upon it at right angles through a glass tube. The direct spark will still appear, but a curious sheet of flame appears to be driven out from it to one side by the blast of air. 39. Magnetic Deflection.— A still more interesting experiment is to arrange a comparatively short sparking dis- FlG. 24. — Magnetic Deflection. charge as above, and to adjust across it the poles of a powerful electro-magnet a...s in Fig. 24 ; this latter must of course be excited by a branch or shunt wire, or by a separate battery. As soon as the current excites the electro-magnet, the spark is con- verted into a luminous sheet, deflected into a crescentic shape, from the outer edge of which issue beautiful luminous rays or streaks. If the current is reversed in either the coil or the electro-magnet, the sheet of flame is deflected in the opposite direction. 40.
