Abstract
The stability of the flow inside an electromagnetically levitated drop is studied numerically using a spectral code. In the uniform or almost uniform external alternating magnetic field the first instability of the flow is three-dimensional with an azimuthal wave number of m=3. The corresponding critical Reynolds number varies from 108 to 81 for various skin depth δ. Figs 7, Refs 23.
