PEMF (Pulsed Electromagnetic Field)

Physics
A technology that delivers time-varying electromagnetic pulses to the body at specific frequencies and intensities. Unlike static magnets, PEMF creates dynamic fields that induce microcurrents in tissue according to Faraday's law of induction. These induced currents are proposed to interact with cellular membrane potential, ion transport, and metabolic activity. PEMF is used as a wellness modality, commonly for recovery, circulation, and general wellbeing. Devices range from low-intensity systems for surface and wellness use to high-intensity systems built for deeper reach.
Where PEMF sits on the electromagnetic spectrumThe electromagnetic spectrum from extremely low frequency up through radio, microwave, infrared, visible light, ultraviolet, and beyond. PEMF operates at the extremely-low-frequency end, far below visible light.ELFRadioMicrowaveInfraredVisibleUVX-rayGammaPEMF is hereLower frequency, longer wavelength on the left; higher frequency on the right.© 2026 Gauss Labs
PEMF sits at the extremely-low-frequency end of the electromagnetic spectrum, pulsing a handful to a few thousand times per second. That is far below radio, and far, far below visible light. At these low frequencies the body barely absorbs the field, which is why reach is set by geometry, not by tissue.
