e direction of the magnetic field surrounding the wire.Another phase of the relation is the fact that a current flow-ing around a coil in a counterclockwise direction produces a northmagnetic pole. In Fig. 1 the current around the single turn ofconductor is counterclockwise and the magnetic lines… … T Fig. 2. Direction of Magnetic Lines of Forcewith Relation to Current Magnetic Lines of Force. The idea of magnetic lines of forceis a very helpful one, and the direction of the lines may beascertained by employing a small compass needle, the N end ofwhich will always point in the direction of the…
