Abstract

We construct a new class of spinning magnetic string solutions in fR gravity with constant scalar curvature These solutions which produce a longitudinal magnetic field have no curvature singularity and no horizon but have a conic geometry with a deficit angle We also generalize this class of solutions to the case of spinning magnetic solutions with one rotation parameter We find that the spinning string has a net electric charge which is proportional to the rotation parameter With choosing a suitable counterterm we remove the divergences of the action The conserved quantities of the solutions are also calculated by using the counterterm method
