Present study reports on magnetostatic interactions in highly-ordered arrays of Ni nanowires embedded in nanoporous alumina membranes. We use two techniques supplying complementary information : ferromagnetic resonance, FMR, studies from which we derive information of the whole array of nanowires, and magnetic force microscopy, MFM, that informs us about the magnetic state of individual nanowires. From FMR study of the angular dependence of resonance field and its line-width it is concluded that the magnetostatic interaction plays an important role to decrease the effective anisotropy field of individual nanowires. This is confirmed by analysis of MFM images at remanence and its comparison with vibrating sample magnetometer measurements.
