• We present an analysis of the magnetic field structure found in a set of four general relativistic 3D MHD simulations of accreting tori in the Kerr metric with different black hole spins. The global structure of the system is described in terms of five separate regions, and each region has a distinctive geometry of magnetic field. As the black hole spin increases, the tightness of the azimuthal winding of field-lines around the event horizon grows sharply as the frame-dragging enforces rotation in the Boyer-Lindquist frame. The electro-magnetic stress associated with this winding field-lines becomes essential in the outward angular-momentum transfer when the black-hole rotates faster.
