1. A system for electrical attachment of a module to an electrode system comprising:

  • an electrode system comprising;

    a first electrode having a first electrode contact surface;

    wherein the first electrode comprises a ferromagnetic material;

    a module comprising;

    a housing;

    an electrical interface;

    wherein the electrical interface comprises;

    an electrical contact spike;

    wherein at least a portion of the electrical contact spike is capable of movement relative to the housing;

    a magnetic structure;

    wherein the magnetic structure comprises;

    a permanent magnet;

    one or more ferromagnetic pole pieces;

    wherein the magnetic structure is operable to provide a magnetic attractive force between the electrical interface and the first electrode that is directed substantially perpendicular to the first electrode contact surface;

    wherein the magnetic attractive force is characterized by a magnetic flux circuit including the permanent magnet, the one or more ferromagnetic pole pieces and the first electrode;

    wherein the magnetic flux is substantially perpendicular to the first electrode contact surface at the electrical contact spike;

    an electrically insulating layer; and

    wherein the electrically insulating layer is positioned to be compressed around the electrical contact spike by the magnetic attractive force when the electrical contact spike is electrically attached to the electrode contact surface.
