Fig. 6.1 shows a thin slice of semiconducting material used in a Hall probe. I I W P Q X S Z R Y Fig. 6.1 (not to scale) Current I passes through the slice in the direction shown. The slice is placed in a uniform magnetic field of flux density B, so that two of its faces are perpendicular to the magnetic field. A steady Hall voltage VH is developed between face PQXW and face SRYZ.
