Drift velocity in hall effect

WebThe Hall Effect. A strip of copper is placed in a uniform magnetic field of magnitude 2.5 T. The Hall electric field is measured to be (a) What is the drift speed of the conduction electrons? (b) Assuming that electrons per cubic meter and that the cross-sectional area of the strip is calculate the current in the strip. In physics, a drift velocity is the average velocity attained by charged particles, such as electrons, in a material due to an electric field. In general, an electron in a conductor will propagate randomly at the Fermi velocity, resulting in an average velocity of zero. Applying an electric field adds to this random motion a small net flow in one direction; this is the drift. Drift velocity is proportional to current. In a resistive material, it is also proportional to the magnitu…
