E-field (Induced Electric Field)

Physics
The electric field generated inside the body when a pulsing magnetic field passes through tissue. As the pulse changes strength, it creates tiny electrical currents in the body's fluids and cells. This is the primary mechanism behind PEMF therapy's effect on tissue. The induced field's strength depends on how quickly the magnetic field changes (dB/dt), not on peak field strength alone. That's why pulse sharpness and rise time matter as much as peak Gauss for effectiveness.
A changing magnetic field induces a circulating electric fieldA schematic of Faradays law: a magnetic field changing through a loop induces a circulating electric field in the tissue. The faster the field changes, the stronger the induced electric field.Induced electric field (E)Changing field(dB/dt)A fasterchange in the fieldinduces a strongerelectric field.© 2026 Gauss Labs
A magnetic field that changes in time induces an electric field in the tissue it passes through. This is Faraday's law, and it is why the speed of the field change (the slew rate) matters more than the field's peak strength: a faster change induces a stronger electric field, which is what stimulates the body.
