pole free to move will rotate round a current. This may be shown experimentally with apparatus like that shown in Kg. 434. The magnet N S is bent so that it may be pivoted on its middle point, the current being brought to an annular mercury cup, A, by means of a wire which dips into the mer-cury,… … Fig. 434. EOTATION OP A MAGNETIC POLE. 545 The rotation of a current round a pole may be shown bypivoting a wire bent in the form of an inverted letter U A(Tig. 435), on the top of a verticalhorse-shoe magnet. The divided currentpasses through the mercury cups B andC, and leaves by the annular cups…
