rified body by the behavior of such a top. Thus,let Fig. 9 represent a balanced gyroscope spinningabout the axis A B^ let the ball at A representthe electrified point, that at B the magnetic pole.Suppose the instrument is spinning with A B 30 ELECTRICITY AND MATTER horizontal, then if witli a… … Fig. 9. point would do if pushed forward in the sameway, and if it were acted upon by a magneticpole at B. MaxweWs Vector Potential There is a very close connection between themomentum arising fiom an electrified point and a LINES OF FORCE 31 magnetic system, and tlie Vector Potential of…
