Ampere's linear current is also applicable to a small linear current. The ring current can be seen as a series of small linear currents. For each small segment of the linear current, the amperometric rule of the linear current determines the direction of the magnetic induction intensity on the central axis of the ring current. The direction of the magnetic induction line on the central axis of the annular current is obtained by superposition. The amperometric setting of the linear current is basic, and the amperometric regulation of the toroidal current can be derived from the amperometric regulation of the linear current. The amperometric constant current of the linear current is also applicable to the magnetic field generated by the linear motion of the electric charge. At this time, the current direction is the same as the positive electric charge moving direction, and the negative electric charge moves in the opposite direction.
