Abstract:
In experiments of strong magnetic field generation by laser irradiating capacitor-coil target, the coil current would be above 20 kA in ~50 ps. The coil resistance under this extreme condition can be obtained by comparing the current from experiments and the numerical model for magnetic field generation, which is three orders higher than that at room temperature. The result is reasonable when the coil resistivity and skin effect are considered. Coil resistance with pulsed strong electric current is important for investigating high magnetic field generation by using capacitor-coil target.
