series magnetic circuit

A magnetic circuit is a closed path for magnetic flux. Unlike an electric circuit where electric charge flows, nothing physically moves in a magnetic circuit. Instead, the magnetic field is confined within materials like iron cores and air gaps, forming a complete loop.12

In a series magnetic circuit, all the magnetic flux follows a single, unbroken path. This is analogous to an electric circuit where current flows through a single loop. The relationship between magnetic flux ((\Phi)), magnetomotive force (mmf, (f)), and reluctance ((r)) is described by the equation (\Phi = f/r). Here, mmf is like voltage, driving the flux, and reluctance is like resistance, opposing it.1
