The local magnetic field is shown to oscillate at its Alfvén resonance frequency(ies) in response to a wide band source whose frequency range covers the resonance frequency(ies). The proposed mechanism explains certain observations of magnetic pulsations where the frequency is found to vary continuously as a function of latitude for a given event.
