Question

Use the following figure for the next problem.

-A metal strip 1.5 cm wide and 0.20 cm thick carries a current in a uniform magnetic field of 1.5 T. The Hall emf is 5.3 $\mu$V. The drift velocity of the electrons in the strip is approximately

Quizplus · Accepted Answer

The Hall effect equation is given by:

E = VB/RH

where E is the Hall emf, B is the magnetic field, V is the drift velocity of the electrons, and RH is the Hall coefficient.

Rearranging this equation gives:

V = E/RH*B

Substituting the given values:

V = (5.3x10^-6 V)/(1.5 T * 1.5x10^-8 m^3/C) = 0.24 mm/s

Therefore, the answer is B.
