A thin metal film of length 1.20 cm, width of 0.300 cm, and thickness of 31.0 micrometers is used to measure the Hall effect. A current of 2.20 A is maintained along the length of the sample. The Hall voltage of 26.8 microVolts is detected across its width, when a magnetic field of 2.00 Tesla is applied normal to the film.

a. Calculate the drift velocity of the charge carriers.

b. Assuming the charge carriers are electrons, calculate their density.

c. By measuring the voltage drop along the sample, the resistivity of the metal was found to be 3.00·10-8 Ω-m. Find the ratio of the Hall electric field to the electric field responsible for maintaining the electric current through the sample.

Preparing for exam. Please show work and equations used!! Thank you!!

The Hall Voltage is the potential created across a current-carrying metal-strip when the strip is placed in a magnetic field perpendicular to the current flow in the strip. It is used as a research tool to probe the movement of charges in materials, as well as determining the blood flow rate. One fundamental use of the Hall effect is the determination of the charge of the charge carriers. What of the following statements is true concerning the strips with a...
