Beschreibung:
<jats:p>A new mechanism of laser plasma generation of current along an irradiated conductive target, and a considerable (more than 1000 times) enhancement of magnetic field outside the plasma has been found. This mechanism is realized in experimental configurations with spatial asymmetries of target dimension scale. Such asymmetries with the largest possible scale was found to be the main factor that determines electromagnetic phenomena detected by external probes outside the laser plasma.</jats:p>
