文摘A special transformation is found to solve the Magnetohydrodynamic equations,by which two classes of exactanalytic time-dependent solutions of magnetic annihilation for incompressible magnetic fluid have been obtained.The solutions derived here possesses scaling property with time t as the scale factor.We find that the currentcan perform the soliton-like behaviour in the case of asymmetric inflow.The relevant evolution characteristics inthe process of magnetic annihilation are also revealed.
