Physical model of particle interaction. A physical model of particle interaction as a function of the concentration of nanofluids during MNFH considering magnetic dipole interaction energy (Edip), magnetic potential energy (Ep), magnetic exchange energy (Eex), and magnetization reversal of each nanoparticle under AC magnetic field by spin rotation enabling to elucidating concentration-dependent oscillation behavior of SLP changes. (a,b) Summary of experimental results (a) and possible particle interaction models (b) at the AC magnetic field interpreted by means of interparticle distance (dc–c).
