it is advisable to treatthese cases separately. A. Plates moving in a Straight Line. We introduce the co-ordinates ^, rj, f,whose connection with x, y, z is shown\? in Fig. 7. The direction of i; is the positive direction of motion. We shall suppose the inducing magnets inside the sphere, i.e. on… … Fig. 7. and further replace by 0, e ^^^■IM- INDUCTION IN EOTATING SPHERES 55 Thus 1 , COS ^(u become e~^, cos rrj.
