Input (English): In ferromagnetic materials, a version of this effect occurs in which the resultant resistivity predicted by this effect contains an additional zero-field term proportional to the magnetization. Arranging two solid-state elements which demonstrate this effect at right angles to each other and summing their output voltage to eliminate the noise is a typical way of producing a magnetic field sensor using this effect. This effect is derived by noting that the current crossed with the magnetic field creates a transverse current, which results in a potential difference. For ten points, identify this classical effect in which charge flowing across a transverse magnetic field results in an electric field component orthogonal to both the current and the magnetic field, often used to measure the sign of charge carriers.
Output (English): Science
