Short summary
We present a new technique which can be used in devices measuring the viscosity of a liquid. To this end, a steel ball is submerged in the liquid and levitated by magnetic forces. The ball's position is measured and controlled to keep the ball in a stable levitated position. The ball is then actuated to perform a circular motion through the liquid. This motion is measured and can be used to draw conclusions about the liquid's viscosity.
