Cavity optomechanical systems have become a popular playground for studies of controllable nonlinear interactions between light and motion. An alternative scheme with much smaller footprint is provided by magnomechanics, where phonons interact with magnons, instead of photons. Here, we consider the magnomechanical interaction occurring in a suspended magnetic beam, a scheme in which both magnetic and mechanical modes physically overlap and can be detected and also driven individually. We show that a sizable interaction - originated from both magnetoelastic and demagnetizing coupling - can be produced if the beam has some initial static deformation.
