A thin slice of conducting material is placed normal to a uniform magnetic field of flux density B, as shown in Fig. 8.1. [Figure 8.1] The magnetic field is normal to face CDEF and to face PQRS. A current I passes through the slice and is normal to the faces CDQP and FERS. A potential difference, the Hall voltage V_H, is developed across the slice.
