Abstract
This paper presents an electromagnetic velocity (EMV) gauge technique which allows use of conductive samples in the measurement of material velocity subject to shockwave compression. A dynamic model of the induced current in the EMV gauge caused by the conductive samples moving in a uniform magnetic field is developed and the motional emf generated in the EMV gauge is extracted from the measured signal. Experimental results are presented and discussed to demonstrate the effectiveness of the technique.
