A system for providing current to perform a surgical procedure includes an electrosurgical device having a conductive cutting wire and a power source with a power cord providing current to the cutting wire from a power source. The power cord and device are connected via a magnetic connection. The magnetic connection includes a device housing coupled to a cord housing, where a magnetic post is received in a recess for mechanically and electrically connecting the cutting wire and an active wire of the power cord. The recess and the magnetic post can be coaxial, with the axes being perpendicular to longitudinal axes of the device housing and the cord housing so that the connection can withstand a force exerted along the longitudinal axis, but a sufficient force transverse to the longitudinal axes and along the axes of the recess and the post can de-couple the magnetic connection.
