# Hopkinson's Law

Hopkinson's law is a counterpart to Ohm's law used in magnetic circuits. The law is named after the British electrical engineer, John Hopkinson. It states that[1][2]$\mathcal{F}=\phi \mathcal{R}_m,$where $\scriptstyle \mathcal{F}$ is the magnetomotive force (MMF) across a magnetic element, $\phi$ is the magnetic flux through the magnetic element, and $\scriptstyle \mathcal{R}_m$ is the magnetic reluctance of that element.
Here's where I pretend I truly understand what this means. But I really posted this because I share a surname with the law's discoverer and I like the ring of it - Hopkinson's Law. Although, what if I too discover my own scientific law by some curious turn of events? What will mine be called?
