We show theoretically that anisotropy of electronic distribution function inside the laser-irradiated metal leads to the formation of edge currents at the timescale of distribution isotropization. When the electronic pressure in the skin-layer is anisotropic, pressure gradient appears to be non-potential force effectively producing low-frequency magnetic field. In typical experiments with femtosecond laser pumping generated internal magnetic field can rich magnitude up to ~1 Tesla in non-damaging interaction regime. We demonstrate that this field is localized inside the metal, while just a minor part of its energy can be radiated into free space as a sub-terahertz signal.
