Fall Time

Waveform
How quickly the magnetic field collapses after the pulse ends. This affects the strength of the second induction event in tissue as the collapsing field generates a reverse electric field. Measured as the 90%-to-10% transition time of the magnetic field pulse, typically captured with an oscilloscope.
A single field pulse over time, with its rise and fall edges labeledA trapezoidal pulse showing the field rising from baseline to peak, holding, then falling back. The 10 percent and 90 percent levels mark the rise time and fall time; the width at 50 percent of peak is the pulse width; the steepness of the rising edge is the slew rate.90%10%Slew rateRise timeFall timePulse width (at 50%)Time →© 2026 Gauss Labs
One pulse over time. The field climbs from rest to its peak, holds, then falls back. How fast that rising edge climbs is the slew rate, and a steeper edge drives a stronger stimulus. The rise time and fall time are measured between the 10% and 90% levels; the pulse width is measured at half the peak.
