A gyroscopic detection system utilizes magnetic nanoparticles that are suspended in a solution and exposed to a rotating magnetic field. The nanoparticles experience angular deviation from their axes if an external force is applied to the system. Solution composition and oscillation frequency may be varied to optimize the gyroscopic feedback. 1. A sensor comprising:a container;a liquid disposed in the container;a plurality of magnetic particles disposed in the liquid, the magnetic particles defining magnetic poles and moments of inertia;an electrical power source providing alternating electrical current;a plurality of conductive coils operably corrected to the electrical power source such that electrical current passing through the conductive coils generates a rotating magnetic field acting on the magnetic particles and causing the magnetic particles to rotate with the magnetic field whereby the particles define axes of rotation;and wherein angular movement of the coils causes angular movement of the magnetic field, thereby generating a force causing the orientations of the axes of rotation of the particles to change, thereby causing a change in the alternating current to the conductive coils that can be utilized to determine at least one of angular position, angular movement, and angular acceleration of the coils.2. The sensor of claim 1 , wherein:the magnetic particles comprise nanoparticles.3. The sensor of claim 1 , wherein:the container defines a cuboid rectangular inner cavity.4. The sensor of claim 1 , wherein:the plurality of coils comprises first and second coils disposed about first and second axis, respectively, and wherein the first and second axes are transverse relative to each other.5. The sensor of claim 4 , wherein:the first and second axes are orthogonal relative to each other.6. The sensor of claim 4 , wherein:the electrical power source provides first and second alternating currents to the first and second coils, respectively, and wherein the ...
