How quickly the magnetic field reaches its peak strength during a pulse. Faster rise time means a sharper pulse edge and stronger tissue stimulation. This is one of the most important pulse characteristics for effectiveness. Measured as the 10%-to-90% transition time of the magnetic field pulse, typically captured with an oscilloscope.
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.
