Abstract
An apparatus comprises a first induction section comprising a first core and a first coil on the first core. A second induction section comprises a second core and a second coil on the second core. The first core comprises rail extensions, where at least two of the rail extensions extend from opposite ends of the first core. The second core comprises shoe portions located at respective ones of the rail extensions, where a gap is provided between each of the rail extensions and respective ones of the shoe portion. The second induction section is configured to move relative to the first induction section in a path along the extensions. The first induction section is configured to induce current in the second induction section, including when the second core moves relative to the first core along the extensions, to provide a contactless induction coupling between the first induction section and the second induction section.
