Question

(b) The Hall probe is now returned to its original position, a distance d from the wire.
At this point, the magnetic flux density due to the current in the wire is proportional to the
current.
For a direct current of 4.0 A in the wire, the reading of the Hall probe is 3.5mV.
The direct current is now replaced by an alternating current of root-mean-square (r.m.s.)
value 4.0 A. The period of this alternating current is T.
On the axes of Fig.5.3, sketch the variation with time t of the reading of the Hall voltage V for
two cycles of the alternating current. Give numerical values for VH, where appropriate.
