58 Thursday Oct 6th 1843 The effect in the last experiment may be explained by considering that the induction down the wire when placed at the bottom tends to invert the current by induction in the vertical conductor. [[diagram Leyden jar capacitor with wire halo connected to metal band around base of jar and wand]] With the arrangement shown in the anexed figure, no current was produced, or at least I should say, no development of the magnetism took place. ___ When however the circuit was opened, and the discharging wire attached to the ____ The weather to day is so [[impossible?]] for electricity that I have directed Sam to change four of the Daniel batteries. Placed around the room a strap of copper, and over this at the distance of three feet a wire of three [[spires??]] into which a set of magnetizing spirals was introduced, but no effect was produced, when a current was passed through the strap or ribbon from a Daniels battery of 4 elements. Hence the induction from galvanism in a short coil is much less intense than from the discharge of Lyden jar. [[end page]] Monday Oct. 9 59 [[Annotation in margin]] This result cannot be obtained by the discharge of a jar, but by two balls one + and the other minus. [[/End of annotation]] [[Diagram showing ball a[positive charge] and a ball b[negative charge] with current flow from point f to point e moving left to right. above the a ball on top of the flow line is a d marked negative and over the b, a c marked positive with arrows denoting counter flow between c and d]]. Repeated the experiment given at top of last page, found the result as shown in the diagram. [[underline]] a [[/underline]] and [[underline]] b [[/underline]] are two balls connected with the outside and inside of a jar. When the discharge is made, currents are produced towards [[underline]] d [[/underline]] from each direction, and [[strikethrough]] towards [[//strikethrough]] from C in each direction. When the discharging wire connected with the earth is connected with the point [[underline]] e [[/underline]], the current is downward, but when it is connected with f it is also downward, but this effect is due in all probability to the actions on the part of the wire between [[underline]] d [[/underline]] & [[underline]] c [[/underline]], the sum of the actions tend to send the current in the direction of [[underline]] c [[/underline]] [[underline]] d [[/underline]]. Exp.2 See vol.2. p282 June 6th 1842 [See vol.2. p282 June 6th 1842]] [Diagram of Leyden jar with wand positive at top negative at bottom, wire joint on left, wire with direction arrow downward at resistor mark]] When this arrangement was made, which is shown by the anexed figure, the current was downward [[crossed out]] and this was probably due to the action of the releving of the tension of the redundant electricity of the inside [[/crossed out]] Exp.3 [[Diagram of Leyden jar with wand with square drawn behind top metal ball in jar, with wire running downward with variable resistor on wire marked b]] Next arranged the apparatus with the wire leading to the earth at top, but contrary to my expectation, the current as indicated by the needle, was towards the earth. Tried this many times in succession with needles no 5, in all the spirals of the set the result always the same [This result is in accordance with the exp on top of page 61. The whole charge passes through the knob.] Thinking the effect was due to the return wave, I used needles of a larger size No 1 and placed these in the least compound part of the set of spirals, but the effect was the same, the needle was still magnetized so as to exhibit a current downwards.
