Current (A)

The flow of electric charge through a PEMF coil, measured in Amperes. Current contributes to field strength (more current generally means a stronger magnetic field), but it's not a reliable measure of performance on its own. Two devices with identical current can produce very different field outputs depending on coil design, number of turns, rise time, and circuit topology. Gauss and slew rate, not current, describe what the body actually receives.
