Voltage (V)

The electrical potential difference driving current through a PEMF coil, measured in Volts. Higher voltage increases the rate of current rise in the coil (dI/dt). That in turn increases the rate of magnetic field rise (dB/dt) and therefore slew rate. However, voltage alone isn't a reliable measure of PEMF output. Two devices with identical drive voltage can produce vastly different field strengths depending on coil design, number of turns, core material, and circuit topology. Gauss and slew rate, not voltage, describe what the body actually receives.
