The invention provides a hollow iron core coil for transcranial magnetic stimulation. The coil is composed of a hollow iron core and a coil body wound outside the hollow iron core, and the iron core is made of an iron-based amorphous soft magnetic material or a nanocrystalline soft magnetic material, so that the maximum value position of the coil axis magnetic field is not on the surface of the coil but at a certain point, a certain distance away from the surface of the coil, in a space; the target point can be accurately stimulated, the possibility that unrelated nerve tissue is stimulated isobviously reduced, scalp sting is relieved, and meanwhile, due to the high magnetic conductivity of the iron core, the current in the magnetic stimulation coil can be small, and the heating amount issmall.
