The magnetohydrodynamic behavior of shock-generated pulses of plasma ('plasmoids') in encounter with an applied magnetic field is studied. Reflection and transmission of the plasmoid shock front is revealed as well as the existence of Joule heated zones which are convectively unstable. It is shown that strong interaction plasmoids are not delimited by shock front and following contact surface rather, they develop their own internal, evolving structure under the mutual influence of self Joule heating, and induced magnetic field. As a result, the interaction zone behind an ionizing shock wave will progressively decouple from the shock front and follow a trajectory given by the particle motion of the gas rather than the wave motion of the shock front.
