  <dc:title>Unpublished diagram, horseshoe magnet by W F [William Ford] Stevenson</dc:title>
  <dc:description>A small diagram of a horseshoe magnet, upon which Stevenson has labelled the flow of a current up each side of the horseshoe. Stevenson explains that the magnet 'from having two north poles must necessarily have two currents [...] which is the same thing as if two ordinary magnetic bars were united at their south poles and then formed into the shape in question'.
