ИСТИНА

Magnetic reconnection is a fundamental process in a magnetized plasma for changing the magnetic connectivity of plasma elements and for converting magnetic energy to plasma kinetic energy, heat and fast-particle energy. In Sun’s atmosphere it is thought to play a key role in producing solar flares. Here we numerically with a help of MHD code study the nonlinear evolution of magnetic field reconnection in plasma configuration in the neighborhood of a critical point. The special attention is devoted to the case of structurally unstable magnetic field.
