It is shown that the relativistic ponderomotive force of intense circularly polarized Laguerre–Gaussian electromagnetic beams can create the space charge electric field, which sets differential motions of the electrons and positrons in an electron–positron plasma. The resulting plasma current, in turn, creates quasi-stationary magnetic fields due to Faraday's law.
