Magnetic Hyperthermia Treatment (MHT) continues to occupy clinicians, and experimental & theo-
retical magneticians alike. The many modelling approaches for non-interacting magnetic nanoparti-
cles(MNPs) were outlined by Carrey et al. [1] at ICCSAMC 2014 in Dresden. Several authors have
outlined the important role interparticle interactions are likely to play in MHT for closely spaced
particles [1{6]. Modelling of MHT for non-interacting MNPs through the Landau-Lifshitz-Gilbert
(LLG) equation was undertaken by Ch^atel et al. [7].
Our aim is to incorporate the dipole-dipole interactions in the LLG analysis. The e�ects of interactions
on the frequency response of the heating mechanism are presented for two identical MNPs
