Abstract
An effect of the DC magnetic field directed horizontally and imposed over an electromagnetically levitating droplet of liquid metal is studied via temperature measurements at the equatorial and polar parts of the droplets of Ni and Cu. It is demonstrated that while the application of the DC magnetic field lower than 3.5 T destabilizes the droplet, a DC magnetic field of 4.5 T stabilizes the position of the droplet that provides less noisy temperature measurements. However, there is no clear evidence of the damping of the convective heat transport inside the droplet. Figs 7, Refs 10.
