n the poles of the magnet, the lines of magnetic forcetraverse the disc in a direction at right angles to the current,and the result is that the disc is set into rotation, whichcontinues so long as the current is maintained. The rotation of a current about a current can be illustratedby the… … The trough is surrounded by a horizontal coil of wire,and the connexions are such that a current after traversingthis coil can pass up the fixed stem and then along the twobranches of the wire BG, BD, andaway again through the liquid in the 98 trough. The fixed coil produces a magneticfield whose…
