A velocimeter for measuring the velocity field characteristics of a conductive fluid moving over a surface is provided. A magnet has a central axis that is aligned with a direction of fluid movement of interest such that a plurality of magnetic flux lines extend generally normal from the surface. A plurality of electrode pairs provide electrical output signals that are proportional to variations in the magnetic flux lines as the conductive fluid flows there-through in accordance with Lorentz forces. Each electrode pair is disposed symmetrically about the central axis of the magnet. The plurality of electrodes are mounted in a fixed relation with the magnet. The electrical output signals from the electrode pairs are processed and displayed as the velocity field characteristics of the fluid in the direction of interest.
