The cosmic solenoid is modeled by an elastic superconductive surface which separates the Melvin core from the surrounding flat conic structure. We show that a given amount $\\Phi$ of magnetic flux cannot be confined within a cosmic solenoid of circumferential radius smaller than $\\frac{\\sqrt{3G}}{2\\pi c^2}\\Phi$ without creating a conic singularity. Gauss-Codazzi matching conditions are derived by means of a self-consistent action.
