We investigated dynamics of giant flux jumps, caused by thermomagnetic avalanches, in superconducting disc of conventional NbTi-50% superconductor. We studied surface magnetization, as well as changes of magnetic flux in the superconducting sample and in the area around it. The influence of the magnetic history on the flux jumps structure was investigated. The most complex structure of the flux jumps was found during sample remagnetization. The comparison between dynamic changes of the magnetic flux in the sample and in the area around it shows that, at the last stage of the thermomagnetic avalanche, a process of magnetic flux redistribution in the superconductor's volume occurs. This process is not accompanied by an entrance of additional flux lines into the superconductor's volume.
