Design principles are described for continuously operated self supported solenoids in which the mechanical stresses in most of the conducting material are equal and approach its ultimate strength. The results of computations for a number of hypothetical solenoids are summarized showing the power, mass and distributions of current density and field intensity. Finally comments are made regarding the practicability of building such solenoids and providing the power to energize them.
