Resonance

Physics
When a system absorbs energy most efficiently because it's being driven at just the right frequency, like pushing a swing at the moment it naturally swings back. In PEMF, some researchers believe that specific pulse frequencies may resonate with cellular processes, though the science is still evolving. Resonance occurs when the driving frequency matches the system's natural oscillation frequency.
A measured field pulse with its amplitude and ringingA field-versus-time trace of a real damped-sine pulse. The field jumps to a peak, the amplitude, then rings up and down in a fast, shrinking oscillation before settling. The time from one ring peak to the next is one cycle of the ring frequency.AmplitudeOne ring cycleTime →Field© 2026 Gauss Labs
A real field pulse over time. The height of the pulse is its amplitude, how strong the field gets, separate from how often the pulse repeats. After the pulse the coil rings, a fast shrinking oscillation at the coil's natural frequency; the time from one ring peak to the next is one cycle of that ring frequency. A coil driven at its natural frequency takes up energy most efficiently, which is resonance.
