Magnetic field saturation in the Riga dynamo experiment.

Detection of a flow induced magnetic field eigenmode in the riga dynamo facility.

In a closed volume of molten sodium an intense single-vortex-like helical flow has been produced by an outside powered propeller. At a flow rate of 0.67 m(3)/s a slowly growing magnetic field eigenmode was detected.
