Description
Summary:	•Torsions of cylindrical viscoelastic bodies in a magnetic field are investigated.•The Kelvin–Voigt model is used to process the experiments.•Dependencies of shear and viscosity coefficients on field intensity are obtained.•Residual deformations are discovered for the samples with ferroparticles. The torsional deformations of cylindrical bodies with magnetizable elastomers in a uniform magnetic field are investigated. The model of a viscoelastic material, which takes into account residual deformations (a generalization of the Kelvin–Voigt model), is used for a theoretical research. The sample elongation is described by the Mooney–Rivlin model. The dependence of shear and viscosity coefficients and of residual deformations on the magnetic field intensity is determined from a comparison of theoretical and experimental results.
