- Abstract
General expressions for a conservative force of the fluctuational-electromagnetic interaction between a neutral spherical conducting nanoparticle and a smooth surface of condensed medium are obtained for the first time with allowance for both electric and magnetic components. The results of calculations performed for a copper particle interacting with a copper surface show that the contribution of the magnetic components is predominating for all distances from the surface exceeding the particle radius R. The contribution due to the near-surface modes, which is proportional to the temperature and inversely proportional to the cube of the distance, is predominating at distances above ∼10 R.
