| contents | The possibility of significant increase of generated pulsed magnetic fields by the inductor system of a single-turn solenoid and magnetic flux concentrator without initialization of low-cycle fatigue mechanism is theoretically studied by varying the size of the inductor system, the material of the concentrator and the parameters of the discharge circuit. The analysis is carried out on the basis of self-consistent solution of the equation, which describes dynamics of the discharge electric circuit, with equations describing spatial distributions of magnetic and temperature fields, mechanical stresses and deformations in the inductor and concentrator. It is shown that for traditionally used steel concentrators by varying the electrical resistance of the circuit it is possible to increase the amplitude of generated pulsed magnetic fields without the threat of concentrator destruction by about 25~\%, from 32 to 40~T. |
