An infinitesimally thin solenoid carrying quantized magnetic flux n=nbc/e cannot be detected by point particles. However, if encircled by their world sheets, such a solenoid need not stay invisible to charged superconducting closed strings. A novel reparametrization-invariant effect, sensitive to the total (gauge-invariant) magnetic flux penetrating through the test loop, is derived. Borrowing the Kaluza-Klein language, it reflects the interplay between the periodicity of the world sheet and the x5 periodicity of space-time.
