cTMS electric field pulse waveforms for pulse durations of 30 and 120 µs, referring to the duration of the first dominant phase of the electric field, recorded with a search coil and normalised to the maximum amplitude recorded with the 30 µs pulse. The pulse amplitude was limited by the cTMS device to 100 and 37 percent of maximum amplitude for 30 and 120 µs pulses, respectively [9], [10].
