When a static magnetic field and a crossed oscillating field are applied, the deformation rate at a boundary between a fluid and a porous medium depends on the amplitudes of the applied magnetic fields, electric conductivity, porosity, and permeability. The first circuit portion is populated with electronic components and the second circuit portion is populated with at least a compass sensor. The device further having electrical contacts for coupling to an external power source and capable of inducing electro-kinetic manipulation of the gel based reagents and DNA extracted from the sample throughout the device.
