Illustration of Vortex Flow Around a Central Axis - Physics Concept Diagram #3343837 (License: Personal Use)

This black-and-white schematic shows a vertical rod penetrating a flat rectangular plate, with concentric curved arrows and stippled shading forming a spiral pattern on the plate’s surface-indicating rotational motion such as a vortex in fluids or magnetic field lines around a current-carrying conductor. The upward arrows on the rod suggest axial movement or current direction, reinforcing the physical interpretation of induced circulation via the right-hand rule or conservation of angular momentum.

Commonly used in physics textbooks, educational websites, or lecture slides to explain concepts like vortex shedding, Ampère’s circuital law, or rotational symmetry in fields; targets students and educators seeking visual reinforcement of theoretical principles.
