  We study the interaction between the microstructures of Hayward-AdS black
hole using Ruppeiner geometry. Our investigation shows that the dominant
interaction between the black hole molecules is attractive in most part of the
parametric space of temperature and volume, as in van der Waals system.
However, in contrast to the van der Waals fluid, there exists a weak dominant
repulsive interaction for small black hole phase in some parameter range. This
result clearly distinguishes the interactions in a magnetically charged black
hole from that of van der Waals fluid. However, these sort of interactions are
characteristic for charged black holes since they do not dependent on magnetic
charge or temperature.
