A mathematical model of a toroidal inductor with a flat ring core made of a polycrystalline magnetostrictive ferromagnet capable of oscillations was developed, as well as a method of measuring the material constants of a polycrystalline ferromagnetic core based on the resonance frequencies of radial oscillations of a ring placed in a toroidal coil. Material constants are understood as a set of the following quantities: components of the tensor of the modulus of elasticity of a demagnetized ferromagnet, components of the tensor of magnetostrictive constants, and components of the tensor of the magnetic permeability of a ferromagnet.
