In a Hall-effect experiment, a current of 3A sent lengthwise through a conductor of 1 cm wide, 4 cm long,

and 10 μm thick, produces a transverse (across the width) Hall potential difference of 10 μV when a

magnetic field of 1.5T is passed perpendicularly through the thickness of the conductor.

a) Find the drift velocity of the charge carriers and the number density of charge carriers.

b) Show on a diagram the polarity of the Hall potential difference.
