Abstract
An improved method for measuring the surface tension of liquid metals is proposed. Surface oscillations of an electromagnetically levitated liquid metal droplet are observed by a video camera and digital image processing is used to evaluate the spectrum of oscillations. A discussion of the theoretical background and a description of the experimental apparatus are presented. In addition, preliminary results on an FeNi sample, and an outlook for future experiments, including the measurement of viscosity, are given.
