The bearing of any attractive field is determined as the course that the north shaft of a compass needle indicates when the needle is adjusted in the field. Assume that the course of the attractive field were rather indicated as the bearing indicated by the south post of a compass needle adjusted in the field. Would the right-hand standard for power then give the heading of the attractive

Slide 2

The course of any attractive field is determined as the heading that the north post of a compass needle indicates when the needle is adjusted in the field. Assume that the course of the attractive field were rather indicated as the heading indicated by the south shaft of a compass needle adjusted in the field. Would the right-hand manage for constrain then give the course of the attractive compel on the moving positive charge, or would a left-hand govern be required? The right-hand manage would even now work. A left-hand run would be required.

Slide 3

The course of any attractive field is determined as the bearing that the north shaft of a compass needle indicates when the needle is adjusted in the field. Assume that the bearing of the attractive field were rather indicated as the heading indicated by the south shaft of a compass needle adjusted in the field. Would the right-hand lead for drive then give the bearing of the attractive compel on the moving positive charge, or would a left-hand govern be required? The right-hand run would at present work. A left-hand run would be required.
