Question:

In a Hall-effect experiment, a current of 3.0 A sent lengthwise through a conductor 1.0 cm wide, 4.0 cm long, and 10 pm thick produces a transverse (across the width) Hall potential difference of 10μV when a magnetic field of 1.5 T is passed perpendicularly through the thickness of the conductor. From these data, find

(a) The drift velocity of the charge carriers and

(b) The number density of charge carriers.

(c) Show on a diagram the polarity of the Hall potential difference with assumed current and magnetic field directions, assuming also that the charge carriers are electrons.
