    Searching invisible helical dynamos in a cylinder

  • Original language description

    A "invisible dynamo" is a dynamo which operates in an electrically conducting region surrounded vacuum and which generates a magnetic field which is trapped in the electrically conducting region so that no magnetic field exists in the vacuum. Consequently, observations from outside the conducting region are unable to detect this dynamo. The search for an invisible kinematic dynamo is started in an infinite cylinder with periodic boundary conditions along the axis. The first results suggest that invisible magnetic decay modes exist in cylinders, but that no invisible growing field can be supported by the dynamo mechanism.

    Hledání neviditelného spirálního dynama v cylindru

  • Czech description

    ?Neviditelné dynamo? pracuje v elektricky vodivé oblasti obklopené vakuem a produkuje magnetické pole, které je uvězneno v elektricky vodivé oblasti. Vnější pozorovatel nemůže toto pole pozorovat ? nemá o něm žádnou informaci. Hledání neviditelného kinematického dynama započalo v neohraničeném cylindru s periodickými hraničními podmínkami ve směru osy. Výsledky naznačují existenci neviditelného magnetického pole, ale toto pole se rychle rozpadá ? nemůže být udržováno dynamem.
