A metal strip 2.50 cm wide and 1.80 cm thick carries a current of 27.1 A in a region containing a perpendicular uniform magnetic field of strength 1.67 T. The Hall voltage across the 2.50 cm width of the strip is measured to be 4.98 μV. Calculate the drift speed of the electrons in the strip. 1.19×10-4 m/s

Find the number density of the charge carriers in the strip (in m-3).

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...

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....
