In a reversed field pinch(RFP), many interesting nonlinear phenomena such as dynamo action and preferential ion heating are observed. It has been believed that ion heating is caused by the discrete dynamo. However, in our STP-3(M)RFP plasma, we find that the dynamo action is generated not by the discrete dynamo but by the global dynamo which continuously generates toroidal magnetic flux in proportion to the plasma current. On the other hand, we also find that the ion heating is observed at magnetic reconnections and that the increase of both the ohmic input power and the toroidal flux are observed almost at the same time. The increase in the toroidal flux is caused by the radial expansion of the core plasma accompanied with the heating, because at that time the negative flux out side of the reversal surface is pushed out of the liner. We have concluded that the increase of the toroidal flux is a result of the heating.
