on Amperes theory (894). ii. When the magnet is withdrawn, the needle of the galvanometer, whichhas returned to zero, indicates the passage of a direct current. Care mustbe taken that the galvanometer is sufficiently far away for the bar magnetto have no direct action upon it. The inductive action… … Fig. 967 is deflected, but returns to zero when the magnet is stationary, and is de-flected in the opposite direction when it is removed. The induction is hereproduced by the magnetisation of the soft-iron bar in the interior of thebobbin under the influence of the magnet. The same inductive…
