The 1 T+ field your thinking of is a static magnetic field. Static magnetic fields don't induce currents (except in rapidly moving objects) and have no known effects on the brain or biology (at least for the field strengths available for MRI, really extreme magnetic fields might cause such effects).
MRI machines also use much smaller modulated magnetic fields during a scan. It's conceivable these could have TMS like effects but as far as I know they don't in practice. I imagine TMS uses fields which are stronger than these since I believe the excitation coils are placed in very close proximity to the head.
