Scheme of electromagnetic fields generation system. An electromagnetic field generation system typically composed of a waveform generator, amplifier, oscilloscope, and Helmholtz coils. Two commonly used electromagnetic fields are presented: (1) pulsed electromagnetic field signal refers to the periodically repeated bursts composed of a certain amount of pulses [37]; (2) the non-pulsed sinusoidal electromagnetic field with continuous sinusoidal waveform. B refers to the magnetic flux density, t represents time. This image was drawn by the authors. Created with BioRender.com
