Abstract [en]

We present a numerical study of strongly nonlinear magnetic vortex-like structures, denoted whistler spheromaks, which have recently been observed in laboratory experiments. The whistler spheromaks are excited with a ring antenna immersed in the magnetized plasma, and are propagating away from the antenna with a constant speed along the ambient magnetic field lines. The wave magnetic field of the spheromaks are of the same order or larger than the ambient magnetic field, and consists of two parts, the poloidal field which is strong enough to reverse the magnetic field in the center of the spheromak, and the toroidal field. We demonstrate numerically that the latter is crucial for the propagation speed and direction of the spheromak, and that the whistler spheromaks are long-lived structures.
