The study has considered a model of a non-contact suspension of the permanent magnet with diamagnetic stabilization of a position in the magnetic field that is created by two holding permanent magnets with horizontal orientation of the magnetic moments. The suspension mockup is created using NdFeB magnets for two variants of orientation of the magnetic moments in relation to an axis that connects centers of the holding magnets. It included measurement of dependences of interaction forces on a distance between the magnets for both the variants. It is found that the calculation satisfactorily describes experimental dependences of the interaction forces on a coordinate even at small distances compared to sizes of the magnets. The obtained expressions for the interaction forces can be used when designing and creating the multi-purpose magnetic suspension systems with an increased lifting force. Keywords: non-contact suspension, permanent magnets, diamagnetic equilibrium stabilization, horizontal levitation system, dipole-dipole interaction
