This theory is tested on the Little Earth Experiment (LEE), a device where optical measurements are performed in a transparent but electrically conducting liquid subject to rotation, magnetic field and buoyancy in a TC geometry. Magneto-Convective patterns are visualised for the first time and we show that the time- and azimuthally- averaged radial flow near the TC boundary follows the theory.
*This research is funded by the Leverhulme Trust project grants (RPG-2012-456 and RPG-2017-366) and access to high magnetic fields at LNCMI-Grenoble (France) is provided by the European High Magnetic Field Laboratory.
