Question

An aluminum strip 10 cm long, 2 cm wide and
    and 3 mm thick. A current flows in the longitudinal direction
    and a field of 0.75 T is perpendicular to the blade. If the potential
    between the two long sides of the blade is 3 micro-Volt, 
    what is the current flowing through the blade? 
    per atom in the material... m-electron = 9.11 x 10 ^-31 kg and
    m-proton = 1.76 x 10 ^-27 kg = m-neutron). We want to use the Hall Effect here.
