rent of electricity in that conductor. Experiment 94. — Take a helix of many turns so arranged that abar magnet may be slipped freely in and out of it (Fig. in), andattach a galvanometer to it. Slowly lower a magnet into the coil and 136 Elements of Physics. note the effect upon the galvanometer.… … Fig. III. We have seen that allelectric currents possessmagnetic properties, andwill deflect a galvanome-ter needle; hence, whenwe move the needle bythe method used above we must infer that a currentof electricity is set up in the conductor. The direc-tion of the current through the conductor…
