16. A system comprising:
at least one sensing unit comprising a sensing element and at least one spatial Lorentz filter, wherein the at least one spatial Lorentz filter includes an input and an output;
wherein the at least one sensing unit is connected to a processor configured for determining a velocity or a position with respect to a magnetic field and/or a geographic position by processing an output signal of the at least one sensing unit; and
wherein the at least one sensing unit is a current-deflection sensing unit, wherein the sensing element is connected at a first end to a current source and at a second end to a current sink, wherein the at least one spatial Lorentz filter is connected between a first side and a second side of the sensing element for detecting a cross-element potential proportional to a velocity dependent force due to coupling of the magnetic field with the sensing element.
