Understanding Magnetomotive Force & Magnetic Circuits

Magnetomotive force (symbolized by F\mathcal{F} or MMF) represents the magnetic potential that drives magnetic flux through a magnetic circuit, analogous to EMF in electrical circuits. According to Ampere's circuital law, F=N⋅I\mathcal{F} = N \cdot I, where $N$ is coil turn count and $I$ is electric current. Measured in Ampere-turns (At\text{At}) in SI and Gilberts (Gb\text{Gb}) in CGS ($1\text{ At} \approx 1.256637\text{ Gb}$). Hopkinson's law relates MMF to magnetic flux via magnetic reluctance: F=ΦR\mathcal{F} = \Phi \mathcal{R}.
