The article describes a new method for measuring the velocity of movement of an object with a magnetic field source. A moving plasma piston in a channel of a magnetoplasma accelerator, which is essentially a moving conductor with current, is considered as an example of such an object. The method is based on the measurement of the difference signal of two induction sensors. The advantage of the method is the presence of a linear dependence between the primary measuring signal (difference signal) and the final informative parameter (the value of the velocity of movement of the conductor with current). The task of simplifying the velocity measurement is solved at the expense of this advantage.
