Abstract: A transcranial magnetic stimulation circuit, a transcranial magnetic stimulator and a magnetic impulse generation method thereof are provided, in which the circuit includes at least two inductance coils, a direct current, a charging and discharging circuit and a controller. The controller controls the inductance coils to synchronously generate magnetic impulses through an electronic switch. The method includes: coinciding central lines of the inductance coils with each other; controller outputting an impulse sequence to control the electronic switch to enable the inductance coils to synchronously generate magnetic impulses; and superposing the magnetic impulses to form the magnetic impulses required by the transcranial magnetic stimulator. The transcranial magnetic stimulator includes a pillow base and the transcranial magnetic stimulation circuit. A containing cavity is disposed in the pillow base.
