Magnetic Interaction of Films with a Harmonic Surface Profile

We presented an analytical solution to the magnetostatic problem of finding the magnetic field strength of a film with a harmonic surface profile, as well as a relation for the scalar magnetic potential of this magnetic field. The energies and interaction forces of a pair of such films in the case of their location under each other and at displacement of the upper film relative to the lower one are calculated, and the vertical component of the force is analyzed as a function of the shear parameter.
