Question

I tried to solve this exercise:

A cubic metal volume of side d =1.5? and density of charge carriers n is moving along y-axis with a constant velocity u =4 m/s. The cube is placed in a magnetic field B-0.05 T along the positive z-axis. (a) Which is the face of the cube has the lowest electrical potential and which one has the highest? Hint: Consider the Hall effect. (b) Which is their difference? What would be the difference if the cube would be made of another metal with carries n2-

Which says to think about the Hall effect, but usually there’s an external current flow when considering this effect, so I tried to solve the exercise in another way. My questions are:

1) did I solve it right (see below)?

2) how can I solve the exercise considering the Hall effect (and Lorentz force) ?

Answer 1

your answers are correct. i have done it using Lorentz force and tried to explian the hall effect within. see if it helps.
