The number densirty of free electrons in copper is 8.47 x 10 ^22 electronss per cubic centimeter. If a metal strip of copper 2 cm by 0.1 cm (thickness), magnetic field pointing up to top of paper, and a current og 10A, fins a) the drift velocity Vsubd and b) the Hall voltage (Assume the magnetic field is 2.0 T.)

The free electrons in the metals moves randomly in all directions with all possible velocities like molecules of a gas but the average velocity is zero and the net charge through any ...

#### Solution Summary

The solution calculates the drift velocity in a strip of conductor and Hall voltage across it.
