  Inclusion of the inductive electric field, ${\bf E}_{\rm ind}$ due to the
temporally changing ${\bf B}$, in magnetic explosions is discussed, with
emphasis on solar flares. Several roles played by ${\bf E}_{\rm ind}$ are
identified: on a global scale, ${\bf E}_{\rm ind}$ produces the EMF that drives
the explosion; the associated ${\bf E}_{\rm ind}\times{\bf B}$ drift is
identified with the inflow of magnetic field lines into a reconnection region;
the polarization current, associated with $\partial{\bf E}_{\rm ind}/\partial
t$, implies a ${\bf J}\times{\bf B}$ force that accelerates this inflow; and
the component of ${\bf E}_{\rm ind}$ parallel to ${\bf B}$ accelerates the
energetic electrons that cause hard X-ray emission and type III radio bursts.
Some simple models that describe these effects are presented. A resolution of
the long-standing "number problem" in solar flares is suggested.
