Fast magnetic reconnection in three-dimensional magnetohydrodynamics simulations

A constructive numerical example of fast magnetic reconnection in a three-dimensional periodic box is presented. Reconnection is initiated by a strong, localized perturbation to the field lines. The solution is intrinsically three-dimensional and its gross properties do not depend on the details of the simulations. ∼30% of the magnetic energy is released in an event which lasts about one Alfven time, but only after a delay during which the …
