Abstract: An apparatus includes a housing having an external surface configured to be placed on a non-magnetic material over-laying a first device comprising a first ferromagnetic or ferrimagnetic material. The apparatus further includes a second ferromagnetic or ferrimagnetic material and/or an electromagnet within the housing. The second ferromagnetic or ferrimagnetic material and/or the electromagnet is configured to generate an attractive magnetic force with the first device. The apparatus is configured to controllably adjust an attractive magnetic force between the first device and the second ferromagnetic or ferrimagnetic material and/or the electromagnet along a longitudinal axis substantially perpendicular to the surface.
