Magnetic field reconnection occurs when two magnetized plasmas, having a sheared magnetic field across their interface, flow toward each other. 1 Its characteristic feature is a modification of the original magnetic field topology that results from the presence in some relatively small region of dissipative processes that convert …
This last expression is yet another way of describing energy conversion processes in electric machinery, as the component of apparent electric field produced by material motion through a magnetic field, when reacted against by a current, produces energy conversion to mechanical form rather than dissipation.
