The interaction of the solar wind with comets was simulated by using a supersonic and super-Alfven flow of a collisionless hydrogen plasma as the solar wind, with a wax ball as the comet. A comparison of these simulations with the ray structure observed in Type I comet tails indicates that the dynamics of the tails depends on their large-scale magnetic field. It is concluded that the force responsible for turning the rays, directed perpendicular to the tail, has an electrodynamic origin, and the experimental data imply a tail field strength B approximately equal to 30-50 gamma.
