Actually it is along the same line as rTMS. The purpose of rTMS is to trigger a depolarization of the cells so as to elicit a motor response. This is how the clinician knows is the EMF intensity is strong enough. The point of this video is to demonstrate that the depolarization of the cell does not have be triggered by high intensity EMF, but rather, can be triggered by low intensity EMF. The difference is that the brain depolarizes itself and is not 'forced' to do so as in rTMS.
So what is your proposed mechanism of action for this "simulation"? It is certainly not the mechanism of action in transcranial magnetic stimulation. TMS is dependent on the voltage induced along perpendicular axons by the high rate in change of current, and so magnetic field, in the stimulation coil to induce a voltage across the axons. For low magnetic fields your pulse timescales would have to be picoseconds or less and the gradients in the B-field even then would be minimal.
Of course magnetic fields reach the brain. There is no such thing as a magnetic shield. Check this: (three letter w).ncbi.nlm.nih.gov/pubmed/7990740
