Abstract
A system for transferring electrical power, data or both, by way of magnetic induction between a first article and a second article. A first electrically conductive coil is integrated in the first article and a second electrically conductive coil is integrated to a second article. A fastener comprising ferromagnetic or ferrimagnetic material is configured to be positioned through the first coil and the second coil to provide an efficient magnetic conductance path between the first coil and the second coil and to removably secure the first article and the second article together. A control circuit selectively energizes the first coil or second coil with alternating current to transfer electrical energy to the other of said first and second coil.
