A powerful current source creates a current I = 5 • 106 A in a thin cylindrical plasma shell, parallel to the axis and uniformly distributed in azimuth. A magnetic field B0 = 0.1 Tesla is previously created inside the shell. The initial radius of the cylinder is R0 = 20 cm. Subsequently, under the influence of current, the shell is compressed along the radius. Assuming it to be ideally conducting, estimate at what radius the acceleration of the shell will change sign.
