Many astrophysical phenomena (such as the slow rotation of neutron stars or the rigid rotation of the solar core) can be explained by the action of magnetic instabilities in the radiative zones of stars. Especially non- axisymmetric instabilities like the Azimuthal magnetorotational instability (AMRI) and the Tayler instability (TI) are appropriate candidates. In order to place the theory of this instabilities on a safe fundament, they have been realized in laboratory experiments. The talk will give details about simulations of liquid metal experiments and its lab realizations, shows results and explains why laboratory astrophysics helps to understand real phenomena inside stars.
