Dynamic properties of magnetorheological elastomers (MREs) with barium ferrite particles in the presenceof crossed AC and DC magnetic fields were investigated. Calculations of the magnetic permeability weremade based on the fact, that the inductance of the coil changes when the coil is filled with the elastomer.Measurements of inductances of an empty coil and the coil with elastomeric core were carried out. Thecore was smaller than the space inside the coil, so it was able to move within the coil. The dependencies ofreal and imaginary parts of magnetic permeability on AC field frequency had resonance peaks at differentvalues of DC magnetic field strength. The sample vibration was considered in frame of the elastic rodoscillations model. The change of dielectric permittivity of the elastomer with conductive particles undermagnetic field (so-called magnetodielectric effect) was also investigated. These effects are the examplesof transformation of the magnetic field energy into the electrical or mechanical energy of the MRE
