A superdirective near field array for transcranial magnetic stimulation includes a plurality of electromagnetic coils or elements arranged in a superdirective array. An excitation source induces an electrical current in one or more of the electromagnetic coils. A controller is programmed to direct or position the elements to generate a magnetic field in an excitation region or regions of a human head or brain. The array coils focus a predetermined current density in the excitation region or regions, and reposition the excitation region to various locations around the head or brain by selectively varying a phase and a magnitude of the electrical current in selected array elements. Also, a method includes providing electromagnetic coils in an array and an excitation source, generating a magnetic field in regions of a brain by focusing a current density in the excitation region, and varying the currents in the elements.
