Page 7 - if an ordinary wire of short length be used as the medium of communication between the two plates of a battery of a single pair of metals, no management will enable the experimenter to obtain an electric shock from this wire ; but if the wire which surrounds an electro-magnet be used, a shock is felt each time the
Page 83 - The strong spark in the single long wire or helix, at the moment of disjunction, is therefore the equivalent of the current which would be produced in a neighboring wire, if such second current were permitted
Page 8 - On the influence of a spiral conductor in increasing the intensity of electricity from a galvanic arrangement of a single pair.
Page 105 - a mode of winding the wire in planes perpendicular to the axis, alternately running from the inner to the outer, and from the outer to the inner diameters of the
Page 6 - I could obtain no evidence by the tongue, by spark, or by heating of fine wire or charcoal; nor could I obtain any chemical effects.
Page 6 - if the action of the battery be very intense, a " spark will be given by a short wire.
Page 8 - the electromotor is broken, provided the ends of the wire be grasped, one in each hand.
Page 84 - wire must be well insulated from the hand in which it is held, or the electricity will be conveyed off and no accumulation be obtained.
