</H2>

<DD> 
Magnetic reconnection is a <B>flow-coupled diffusion process</B> in which <A HREF="../Research_DFAH_III.html#j-based_em", TARGET=_blank><B>cross-field current</B>-based <B>free magnetic energy</B></A> is efficiently converted into <B>thermal</B> and <B>kinetic energy</B>. It is associated with <B>electric field</B> with ∇×<B>E</B> ≠ <B>0</B>, and the electric field is <B>parallel to current density</B> with <B>j</B>•<B>B</B> = 0 (the former condition indicates that <B>magnetic field is time-varying</B>, while the latter <B>magnetic energy is reduced</B>).
