A thin metal film of length 2.20 cm, width of 0.550 cm, and
thickness of 34.0 micrometers is used to measure the Hall effect. A
current of 1.80 A is maintained along the length of the sample. The
Hall voltage of 17.0 microVolts is detected across its width, when
a magnetic field of 1.50 Tesla is applied normal to the film.
1. Calculate the drift velocity of the charge carriers.
2. Assuming the charge carriers are electrons, calculate their
density.
3. By measuring the voltage drop along the sample, the resistivity
of the metal was found to be 2.20·10-8 Ω-m. Find the
ratio of the Hall electric field to the electric field responsible
for maintaining the electric current through the sample.
