## Contribution

It introduces a novel experimental method to simulate ultra-strong magnetic fields in dusty plasmas and validates simulation predictions with experimental data.

## Key findings

- Super-diffusive behavior observed at intermediate time-scales.
- Self-diffusion coefficient depends on magnetic field strength.

## Abstract

The self-diffusion phenomenon in a two-dimensional dusty plasma at extremely strong (effective) magnetic fields is studied experimentally and by means of molecular dynamics simulations. In the experiment the high magnetic field is introduced by rotating the particle cloud and observing the particle trajectories in a co-rotating frame, which allows reaching effective magnetic fields up to 3000 Tesla. The experimental results confirm the predictions of the simulations: (i) super-diffusive behavior is found at intermediate time-scales and (ii) the dependence of the self-diffusion coefficient on the magnetic field is well reproduced.
