Q#02. A strip of copper 150um thick and 45cm wide is placed in a uniform magnetic field
B of magnitude 0.85T, with B perpendicular to the strip. A current i = 2.3 mA is then sent
to the strip such that a Hall potential difference V appears across the width of the strip.
Calculate V. (the number of charge carriers per unit volume for copper is
8.47×108electrons/m³).
The current in a conductor is found to be moving from (4.18, 3.79, 4.20) meters to (7.99, 9.11, 6.74) meters.
