Convention If the voltage of lower terminal is negative, electrons are the majority charge carriers. If the voltage of lower terminal is positive, holes are the majority charge carriers.
Show that, in terms of hall electric field E H, and the current density j, the number of charge carriers per unit volume is given by
Show that the ratio of hall electric field to the electric field is given by
A metal strip 10 cm long, 1 cm wide and 1mm thick moves with constant speed v through a magnetic field of 1mT perpendicular to the strip. A potential difference of 4 V is measured between the points x and y across the strip. Calculate the speed v V d is the velocity of strip now V d = 0.4 m/s
A strip of copper 150 m thick is placed in a magnetic field B = 0.65 T perpendicular to the plane of the strip. A current 23 A is setup in the strip. What hall potential difference will appear across the width of the strip if there were 8.5 x 10 28 electrons/m 3 ?
