Abstract: This paper considers a range of physical phenomena that occur during electrical discharge in water in the presence of a transverse magnetic field. An approximate equation of energy balance is obtained using assumptions based on the well-known hydrodynamic concepts of a long electrical discharge in water. An experimental estimate of the reaction force impulse in a limited medium is obtained.

Keywords: electrical discharge in water, magnetic hydrodynamics, resistance to motion in liquid.
