A spatial vector quantity equal to a potential gradient, produced by charged bodies or a time-varying magnetic field. Unit is volts per meter. The electric field E induced in a loop equals the negative time derivative of the magnetic flux Fgr.gif cutting the loop (dI is a length element of the loop):

Conintr.gif EMiddot.gifdI=–∂Fgr.gif/∂t.


It is also expressed in terms of the change in the magnetic induction B with time t:

Nabla.gif×E=–∂B/∂t.
