Description

This is a LaTeX document that includes several packages such as circuitikz, graphicx, mathrsfs, latexsym, amssymb, and amsmath. The code creates an electrical circuit diagram using the circuitikz package. The circuit consists of a voltage source labeled with the symbol for magnetic flux density ($\mathscr{F}$) connected to a series of resistors labeled with different reluctances ($R\_{a2}$, $R\_r$, $R\_{a1}$, and $R\_s$). The resistors are colored with different colors such as purple, blue, and red to differentiate them. There is a current flowing through the circuit represented by the symbol for magnetic flux ($\phi$). The code also includes a circle with an arrow (in red color) to indicate the direction of rotation of the magnetic field ($\phi$).

Keywords
