Figure 7B.19 - Magnetic Lines of Force developed from induction of current flow.
A = Current carrying wire reaches out to establish concordance in B, C and D via sympathetic outreach. Which concordance creates a secondary and tertiary current flow at 90 degrees to the Outreach through these "lines of force" all via sympathetic vibration.
NOTE: These are not the "lines of force" usually thought of pertaining to magnetic fields.
