The question as text
A Hall probe consists of a slice of conducting material, as shown in Figure 7.1. I I magnetic field, flux density B Q R Y X S P Z W Figure 7.1 Current I enters the slice at face WXYZ and leaves it at face PQRS. The slice is in a uniform magnetic field of flux density B. This magnetic field is perpendicular to faces WXQP and ZYRS. A Hall voltage VH is induced between two of the faces of the slice.
