Abstract

A current-carrying solenoid can be imagined as fitted with slip-joints and flattened into a shape comparable to a parallel-plate capacitor. In this shape it is easy to calculate forces, the work done, and energy changes that are analogous to those for a capacitor with constant charge or constant voltage.
