20.4d Ex2 ON17 P42 Q8 Explaining Hall Voltage | A2 Magnetic Fields | CAIE A Level 9702 Physics

Example 2 - 9702/42/O/N/17: A thin slice of conducting material is placed normal to a uniform magnetic field, as shown in Fig. 8.1. The magnetic field is normal to face CDEF and to face PQRS. The current I in the slice is normal to the faces CDQP and FERS.A potential difference, the Hall voltage VH, is developed across the slice. #9702w17p42 #A2hallEffectP4 #Lv2 (a) (i) State the faces between which the Hall voltage VH is developed (ii) Explain why a constant voltage VH is developed between the faces you have named. (b) Two slices have similar dimensions. One slice is made of a metal and the other slice is made of a semiconductor material. For the same values of magnetic flux density and current, state which slice, if either, will give rise to the larger Hall voltage.
