We have studied the electric resistivity in superconducting amorphous Mo{sub 3}Si films in a perpendicular magnetic field B{sub 0}+B{sub 1}sin{omega}t with B{sub 1}{lt}B{sub 0}. For B{sub 1}=0 a resistive voltage only appeared due to flux creep above the critical current I{sub c}. For B{sub 1}{gt}0 we observed perfectly Ohmic behavior at currents I{lt}I{sub c} (B{sub 1}=0), with the resistivity increasing proportional to {omega} and B{sub 1}. We present a simplified model discussion explaining our results in terms of the magnetic flux transferred across the sample during each cycle of the oscillatory magnetic field because of the electric transport current. {copyright} {ital 1997} {ital The American Physical Society}
