A strip of copper 10 mm wide and 900µm thick is placed in a uniform magnetic field B vec of magnitude 0.30 T, with B vec perpendicular to the strip. A current i = 23 A is then sent during the strip such that a Hall potential dissimilarity V appears across the width of the strip. Compute V. (The number of charge carriers per unit volume for copper is 8.47 multiplied by1028 electrons/m3.)
