The calibration of the B-dot probes for magnetic induction intensity measurement in electromagnetic emission experiments

摘要：

　　In electromagnetic emission, B-dot probes can measure the spatial magnetic field, as well as the armature velocity.In this paper, self-developed B-dot probes are calibrated based on the B-dot probe magnetic induction principle.The working principle of the calibration system is described in detail,andthe calibration data of the B-dot probes are analyzed.Not only does the experiment verify thatthe magnetic field intensity is proportional to the time integral of inductive voltage of the B-probe, but also the sensitivity coefficient of each probe can be calculated through programming.And then, a set of magnetic-field component along rail was calculated through analyzing experimental data sets acquired by armature probes in the electromagnetic rail gun experiment.
