A smooth, continuously curving waveform that produces gradual field changes during each pulse cycle. Sine waves produce symmetrical rising and falling edges, and because the field changes gradually rather than abruptly, they typically produce lower slew rates than square or sawtooth waveforms at the same peak Gauss and frequency. They are often chosen where a gentle, gradual pulse is wanted. Many resonant and capacitor-discharge PEMF circuits naturally produce sinusoidal output.
The shape of each pulse is its waveform. A sine wave rises and falls smoothly; a square wave snaps between two levels; a triangle wave ramps up and down in straight lines; a sawtooth ramps up then drops sharply. The shape sets how sharply the field changes, which is what the timing measurements capture.
