“…Because of these effects, the validity of the measurement procedure via modulated calorimetry realized with the Joule heating produced by the electromagnetic system for terrestrial experiments is under question. In the present work we studied the thermal behavior of the sample using different modulations of the electric current circulating in the inductor to check if the measurement procedure presented elsewhere can be realized [6].…”

Under terrestrial conditions, the temperature behaviour of a sample in levitation may be different from that observed in microgravity. Here we present the temporal evolution of the polar and equatorial temperatures of a levitating charge of Ni, revealed numerically and experimentally for different AC current modulations. It is demonstrated that the motion of the sample during the AC current modulation should be taken into account. Tables 2, Figs 3, Refs 9.

Electromagnetic levitation (EML), a contactless metal melting method, can be used to produce ultra-pure metals and alloys. In the EML process, the levitation force exerted on the droplet is of paramount importance and is affected by many parameters. In this paper, the relationship between levitation force and parameters affecting the levitation process were investigated by dimensionless analysis. The general formula developed by dimensionless analysis was tested and evaluated by numerical modeling. This technique can be employed to design levitation systems for a variety of materials.
