The time-dependent transport through single-molecule magnets (SMM) coupled to mag-netic or non-magnetic electrodes is studied in the framework of the generalized Masterequation (GME) method. We calculate the transient currents which develop when themolecule is smoothly coupled to the source and drain electrodes. The signature of theelectrically induced magnetic switching on these transient currents is investigated. Oursimulations show that the magnetic switching of the molecular spin can be read indirectlyfrom the transient currents if one lead is magnetic and it is much faster if the leads haveopposite spin polarizations. We identify effects of the transverse anisotropy on thedynamics of molecular states.
