Molecular high-order harmonic generation(MHOHG) is simulated for H+2 in the nonlinear nonperturbative regime of laser-molecule interactions with ultrashort intense circularly polarised laser pulses. It is shown that combinations of co-rotating or counter-rotating pulses produce laser-induced Coriolis forces with electron-parent ion recollisions, thus enhancing circularly polarised MHOHG, the source of circularly polarised attosecond pulses. Such pulses can be used to induce electron attosecond currents for the generation of attosecond magnetic field pulses, new tools for molecular attomagnetism.
