6. Conclusion The magnetic-pulse method is an effective and easily adaptive method for creating various loading modes. This method is applicable to the creation of experimental loading systems that make it possible to study the behavior of various materials in extreme conditions at strain rates of 103 – 104 1/s. The developed systems allow you to control the impact on the investigated sample and can be used to study samples of various shapes made from various materials, and the presented analytical model allows you to evaluate the requirements for the parameters of the magnetic system necessary to obtain the specified values of deformation and strain rate. Obtained experimental data correlate with results of analytical solution and proposed predictive model can be used for determination of parameters of magnetic system for uniaxial high strain rate tension.
