This theoretical investigation develops analytical concepts on how to realize magnetic fields for the Multi to Mega Tesla realm within the range from milli to nano volumes and periods. The fields are anticipated to be realized using solenoids with multi-walled carbon (MWCNT) nanostructure composite metal windings. The study presented here opens up the issue of the miniaturization of large magnetic field systems. Concern has been raised that for such large magnetic fields and associated energies that the solenoidal structure may be highly reconfigured. Consequently, an investigation is undertaken of the tensile strength resulting from the azimuthal current. Also, the azimuthal power per turn will be addressed along with its limitations in generating the magnetic field. Further, the study finds the allowable eigenvalue frequencies of the electric field. Tables are provided for given values of B z 0 (0) from 2 T to 2(10) 6 T for a number of important parameters for consideration in designing solenoidal systems.
